Postmark from Vienna

Two lifelong friends turn a casual argument into a high-stakes wager over an ultra-rare postmark. One insists the stamp exists, the other bets it’s a collector’s myth. What begins as a playful challenge soon spirals into a chaotic treasure hunt across flea markets, eccentric auctions, and baffling postal archives. As their rivalry heats up, their friendship is tested—until a surprise discovery forces them to decide what’s truly worth collecting.
