Two stamps and faint postmark are there on this real photo card, along with the writing on the front, but we can’t quite say when the card was mailed.  This town, known for its mineral water and crystal glass, is now in Slovenia.  Grade: 3

You might think it was an ordinary postcard but for this:  mailed in 1958 with three different stamps and two postmarks to the famous American actress Ava Gardner at MGM Studios in Hollywood, asking for something that we can’t really translate.  Can you tell us what “platohusten Jammamne” means?  Card has serrated edges.  Grade: 2

Apart from all the other past and recent historical associations of Sarajevo, we thought we would look up the bridge.  Wikipedia told us this:  “Latin Bridge (Serbo-Croatian: Latinska ćuprija/Латинска ћуприја, named Principov most/Принципов мост – “Princip’s Bridge” in Yugoslav era), is an Ottoman bridge over the river Miljacka in Sarajevo, Bosnia and Herzegovina. The northern end of the bridge was the site of the assassination of Archduke Franz Ferdinand of Austria by Gavrilo Princip in 1914, which became casus belli of World War I.”  As for the card, it was mailed in 1970 with two different stamps, mostly readable postmark, and staining along the upper reverse edge.  Grade: 3

Pula is now the eighth largest city in Croatia — how the world changes — but from this card you might think it was even larger.  Mailed from there in 1974, with Yugoslav stamp and postmark.  Grade: 1

Because of the topic and focus of the museum, we choose to list this series of black-and-white cards under “Yugoslavia” instead of “Serbia,” though the cards date from 2019.  So don’t let the old appearance fool you.  Photo was taken on 25th May 1969, International Youth Day.  Unused card that’s flexible and — yes — magnetic.  We would not put this on our refrigerator, but you could.  Grade: 1

Sourced from Belgrade’s Museum of Yugoslav History, this unused and contemporary B&W card is flexible and magnetic.  The yellow sticker should be able to be peeled off.  Grade: 1
