I found a photo of a stamp collection. They are mostly Slovenian stamps, but you can spot some other too.
There are some from Italiay, former Czechoslovakia, Spain, Germany, Nederland, Bulgaria and so on.
You can try to find more on this photograph. I sure missed a few.
I love receiving postcards from my friend's travels. Unfortunately, they usually forget to send one because it is not that popular anymore. Also, most of my friends do not even travel much. So the postcard collection is not growing very fast.
Have a nice day everyone and Steem on :)
