Professor Balthazar is a Croatian cartoon dating back to the late 1960’s and it’s about the professor Balthazar & his inventions. I remember back when I was a kid, it was one of those cartoons I was looking forward to watching on TV.

And here’s a link to one of the episodes on YouTube (I even managed to find the one in English :D ) https://www.youtube.com/watch?v=L-V0QHltQBc
I’m so happy about these postcards, I love to send them to people! :D
