A small mistake

Few days ago we went walking downtown Sofia with Mr. Strong, when I saw this poster. It was about russian children's character called Cheburashka. I got so inspired, it's a Cheburashka costume party!

The history of Bulgaria is still a bit unknown to me, but I realized the poster was about the exhibition, which again was about soviet socialist times in Bulgaria, seen through the eyes of youngsters of those times. I think I need to learn this language, but at least I have a Cheburashka costume for cold winter days!
