This Slovenian 12-tolar stamp was issued in 1996 to commemorate the 1st Assembly of the Postal Union (1. APU) held in Maribor, Slovenia. Designed by Bronislav Fajon, the artwork features a modernist composition with white doves carrying an envelope, symbolizing peace, communication, and the timeless spirit of postal exchange. The geometric background of red, orange, and black dots contrasts with the silver-grey tone, evoking both digital modernity and traditional postal symbolism. This issue reflects Slovenia’s emergence as a modern postal nation after independence in 1991 and its commitment to international cooperation.
