An interview with Rob Janoff, designer of the Apple logo
Talking about how it was designed:
[P]eople ask me: did you design it on a computer? And of course at the time computers couldn’t really do that for me. It was only years later till the Mac was designed, developed and refined that I even start working on a computer. At the time it was all pencil and paper, glue and cut paper, pens and all that stuff.
