The photos were captured in the Retro Museum, situated in Varna, Bulgaria (link from TripAdvisor, as the site of the museum seems to be dead).
During our summer vacation on the Black Sea, we did a quick trip to Varna as we were at a resort close by. There we stumbled upon a very interesting Retro museum.
I was very pleasantly surprised to find almost all the different things that I used when I was young. So many good memories from my childhood came up while visiting.
Definitely a good place to visit when in Varna!
