Stamps featuring Ukraine's famous mine-sniffing dog Patron earned Ukrposhta about $500,000 (£400,000): 80% of the money was spent on mine-clearing equipment, and the rest on animal shelters.
Another stamp of a mural left by renowned graffiti artist Banksy on a building devastated by shelling outside Kyiv, helped fund 10 bomb shelters. This stamp features another popular but unprintable Ukrainian slogan - this time directed against Vladimir Putin.
