Stefan Kanchev (1915-2001) was one of the most prolific graphic designers to come out of Bulgaria. He’s designed numerous book covers, posters, postcards, advertisements, forms and envelopes, post stamps, labels and packages but he’s widely recognized for his excellent logo work. He’s considered one of the best logo designers along with Saul Bass and Paul Rand.
The simplicity of the logos created by Kanchev is what really stands out for me. They all work in a solid, single color and a minimum amount of shapes and lines are used to create the visual. Stunning.
