Playboy has posted online the text of an interview in this month's issue with Stan Lee. It mostly has to do with Stan's delight at how famous he is, how famous the Marvel Super-Heroes are, etc.
A lot of the history is not only at odds with my understanding but it's different from things Stan has said in the past, both in print and in private conversations. I suspect an upcoming issue of Playboy will feature a letter from Steve Ditko saying much the same thing.
