The Houston Philatelic Society (HPS) hosted Ltc. David S. Ball, the author of American Astro Philately: The First 50 Years, on March 2, 2026. Ball gave a presentation on Ukrainian war stamps, focusing on how Ukraine has used postage stamps as propaganda and morale boosters during the conflict with Russia since 2022. Ball presented examples of stamps depicting defiant gestures, military victories, and symbolic imagery, including the “done” issue that replaced the original stamp after Ukraine sank the Russian ship Moskva. The presentation highlighted Ukraine’s innovative approach to stamp design and production, including public input for new designs and the use of stamps to celebrate military achievements like the destruction of Russian aircraft and submarines. Ball also discussed his upcoming participation in the Boston 2026 World Stamp Expo in May, where he plans to display drone mail created with a friend to support Ukrainian warfighters.
