Ptuj Castle and Ptuj Museums on Postcards

The birthday of the Ptuj Museum is also commemorated with a commemorative envelope, a seal dated August 3, 2023, and a stamp. We prepared the envelope together with the Philatelic Society of Ptuj, which is also preparing a philatelic exhibition on the theme of the Ptuj Museum. This will be on display in the Salon of Art from August 3, 2023 onwards.
