I have mentioned before how the Larry Evans 3-Dimensional maze books in the 1970's started me drawing mazes when I was a kid. Check out this great 2013 interview with his publisher, Malcom Whyte of Troubador Press. Whyte discusses Evans, the other artists he worked with, and running an indie publishing house back in the day. It is a good read.
