While we have certain facts that point to when Stan Lee began working Marvel Method with a few artists, there are questions as to when it was fully initiated throughout the line. I've done a great deal of research on this over the years and have documented my findings here. The earliest known proof of the Marvel method in print is Stan's plot synopsis for Fantastic Four # 1. Evidence points to Lee working this way earlier, most likely with Jack Kirby and Steve Ditko (and possibly earlier with artists such as Joe Maneely). Kirby had done a few earlier stories for Lee in 1956 and 1957, but began working steadily in late 1958 on war, romance, western and fantasy stories, all short stories in anthology titles. The stories were likely plotted by Lee and written by Larry Lieber, although some may have been written by Kirby (more on this on an upcoming Blog post). The first ongoing character Lee worked on with Kirby was the revamped Rawhide Kid, beginning with issue # 17 (Aug 1960)
