A stamp depicting a Ukrainian soldier making an obscene hand gesture at the Russian Black Sea flagship Moskva has become a collector's item for Ukrainians who see it as a sign of "victory".
"That ship was the biggest one they had.... They gambled a lot on it and we destroyed it!" said Yury Kolesan, 22, who waited for two-and-a-half hours to get a set of 30 stamps.
"It's a new phase of the war, one of victory!"Ukraine's postal service last month launched a competition to illustrate the episode.
Out of more than 500 submissions, Lviv designer Boris Groh's winning entry shows a Ukrainian soldier from behind swearing at the warship.
It has proved a hit, selling out in many post offices and quickly appearing for resale online.
"We wanted to print more but the bombing last night in Kyiv affected the work of the factory and we did not manage to print the necessary quantity," Ukrainian postal service Igor Smelyansky told AFP.
