So I actually contacted Edward Summer last year and have met with him and interviewed him over a period of nearly a year. Unfortunately Rinzler printed some of my favorite bits (the sitting on the floor and reading the original Flash Gordon drawings was given a pretty flat delivery for a story as awesome as it is).
I've got the interviews on tape, and will write a big piece at some point when I can find time. For now I've started publishing my Kitbashed project, of which it is a part, at http://kitbashed.com.
