Drone Mail Poster Stamp Perforation Error Pair

These error-pair Drone Mail poster stamps were created specifically for the inaugural Drone Mail covers, marking the first flights just outside Zaporizhzhia on April 16, 2026. During production, the perforating machine was inadvertently run through the center of one stamp row rather than along the standard perforation lines.

Only two sheets with the perforation error were saved, with one being broken apart to create (5) of these error pairs.

All profits from the sale of these blocks will go directly to Azov's 3rd International Battalion.

All poster stamps are hand-designed by U.S.-based artists expressly for S.O.R.A.'s fundraising.
