Charles is very active in the philatelic community. He is the Editor-in-Chief of the award-winning The Chairman’s Chatter, Editorial Proofreader for The Chronicle, Webmaster and Life Member of the U.S. Philatelic Classics Society, and has held Officer and Board roles. He is also the President, Web Designer & Developer and Archivist of the Philatelic Society of Lancaster County (PA), as well as President and Webmaster of the Empire State Postal History Society. Charles served for 9+ years on the Council of Philatelists at the Smithsonian Institution’s National Postal Museum, co-leading the new initiatives committee and contributing to the NPM’s Arago website launched in 2006 – an online resource for the study of philately and postal operations. He is also a Charter member of The Philatelic Gathering founded in West Chester PA in 2018, whose mission is to share the love of philately with others.
He has received numerous honors over the years. Below are a few highlights.
In 2003, he received the U.S. Philatelic Classics Society Lester Brookman Cup, for giving unselfishly his time and effort to transforming the USPCS website into a highly effective electronic gateway for the Society and philatelic community and the American Philatelic Society Spark Plug Award in recognition of his positive impact and achievements in enhancing and growing the Philatelic Society of Lancaster Country, APS Chapter 173. In the 2018 American Philatelic Society Website Award Competition, three Gold Medals (out of 8 awarded) went to websites that Charles developed, designed and currently administers. These are the U.S. Philatelic Classics Society, the Philatelic Society of Lancaster County and the Empire State Postal History Society. This award recognizes website excellence and exemplifies the very best that is happening out in the local stamp and postal history communities.
In 2020, Charles was honored with the American Philatelic Society’s Nicholas G. Carter Volunteer Recognition Award for his National Promotion, Service and Innovation to philately and the hobby. In 2019, he was awarded the APS Article of Distinction for An 1845 “Ship Letter” from Port-au-Prince, Hispaniola to New York City on the Brig Hayti., which was a special feature in the January 2019 Philatelic Society of Lancaster County Newsletter, and subsequently published in the March 2019 Empire State Postal History Society journal Excelsior! You can also view the article and other award winners on the APS website HERE.
In 2020, he was the recipient of the Grand Award & Large Gold in Literature at the Sarasota National Stamp Expo & Writers Unit 30 for his work entitled New Plate Flaw Discovery: “Dash and Ink Trail” on 3¢ 1851 Stamp, which was published in The Chronicle 259 (August 2018), Vol. 70, No. 3, pp 215-217. He also received a Large Vermeil for An 1845 “Ship Letter” from Port-au-Prince, Hispaniola to New York City on the Brig Hayti. He was also honored with the Excelsior! Best Article Award by his peers at the Empire State Postal History Society for his 2019 article entitled From the Front Lines: Lt. Col. William G. Belknap’s First Hand Account of the Battle of Monterrey during the Mexican-American War in 1846. This article also took home a Large Vermeil at the 2020 SESCAL (Stamp Exhibition of Southern California) First Annual Literature Exhibition of Philatelic Articles.
In 2021, Charles was awarded a Gold Medal at the SESCAL 2nd Annual Literature Exhibition, a Gold Medal at CHICAGOPEX 55th Annual Literature Exhibition and a Large Vermeil at the American Philatelic Society Great American Stamp Show’s 53rd Annual National Literature Exhibition for his article appearing in the February 2021 American Philatelist research issue entitled A Noteworthy Precancel on Lancaster Watch Company’s Advertising Covers.
As one person penned, “Dr. DiComo successfully presented his research by weaving the philatelic research of the pre-cancel with a social story of the watch company. The author’s presentation style allowed his research to flow as a historical story instead of a clinical dissertation… The “lesson learned” is that world class philatelic research needs to be multi-dimensional… not only does it need to be well researched, it must be written in a manner that captivates the reader.”
In 2022, Charles was awarded a Large Vermeil at the 3rd Annual SESCAL Virtual Literature Exhibit of Philatelic Articles for his article entitled H.H. Warner & Co. “Safe Remedies” Major Double Transfer of Central Vignette on 6¢ Medicine Stamp, RS258dt, which was published in The American Revenuer, Volume 75, No. 2, 2Q2022 Issue, pp. 59-61.
In addition, he was also awarded a Bronze medal for his article entitled The History of the Ill-Fated Dirigible Akron and the Discovery of a Scarce “Souvenir of Balloon Akron” Fabric Postcard from 1912, which appeared as a Special Feature in the PSLC Newsletter, as well as The Card, the newsletter of the Lancaster County Postcard Club. Congratulations to all the authors and honorees.
Once more in 2022, Charles was recognized with a Large Gold Medal in the APS Star Route competition for his editorial prowess in publishing The Chairman’s Chatter, the Newsletter of the U.S. Philatelic Classics Society. Recently relaunched, this competition judges the various newsletters and websites of APS Chapters. Since the mid-1800s, the Star Routes were the most challenging routes in the country to deliver U.S. mail. Congress called for contractors to deliver the mail with “celerity, certainty, and security,” soon replaced with three stars. Our chapters serve and grow the hobby in those same tough terrains with that same mission. Four times yearly, Charles edits a Chatter containing the activities of the Society. It contains such columns as a letter from the President; various committee reports; members who have won medals at WSP shows; photos taken at recent Society events; etc. Congratulations, Charles!
In 2023, Charles was honored with two Vermeil at the 2023 Sarasota National Stamp Expo & Writers Unit 30 for articles published in philatelic journals in 2022.
The first winning article is A One-Day Wonder: Name of Post Office on Long Island became Jones Beach for a Single Day in 1932. This appeared in The Excelsior!, October 2022, Whole No. 36, New Series, pp. 3-6, the postal history journal of the Empire State Postal History Society, of which Charles is also President. This article was also honored with the Excelsior! Best Article Award 2022 by his peers at the Empire State Postal History Society. The second is H. H. Warner & Co. ‘Safe Remedies’ Major Double Transfer of Central Vignette on 6¢ Medicine Stamp, RS258dt, which appeared in The American Revenuer, Second Quarter 2022 (Vol. 75, No. 2), pg. 59-61.

As one philatelist shared: “Charles successfully presents his discoveries by weaving the philatelic investigation in a presentation style that allows his research to flow as a historical story instead of a clinical dissertation… The ‘lesson learned’ is that world class philatelic research needs to be multidimensional… not only does it need to be well-researched, it must be written in a manner that captivates the reader. Congratulations Dr. DiComo!”
