Absolutely stunning work from Stefan Kanchev (1915-2001) who was a Bulgarian graphic artist. During his prolific career he designed hundreds of logos, posters, stamps, book covers, labels as well as graphics for TV. Much of his work is inspired by Bulgarian folklore and traditions.
In 1994 Stefan Kanchev was recognized as one of the top ten designers of trade marks in the world along with Paul Rand, Saul Bass and etc. The title was awarded by the International trademark centre in Ostend, Belgium. His logo work will blow your wig back. I highly suggest you spend a few minutes browsing his archives.
