What about Steve Ditko?

Rating: Null/10 (5 September 2004)

I just finished watching Spider-Man on DVD. I saw a Japanese bootleg version in a classroom (weird) and then I paid to see it in the theater, but rented the DVD to see the Extra Features.
It's a terrific movie - I was an avid reader of the comic book in the 70s (until some bozo decided to kill Gwen Stacy, and then I felt betrayed and stopped reading it; but that's another story). I'm very happy with the Sam Raimi movie adaptation.
What I want to know is: What happened to acknowledgment of STEVE DITKO? Ditko drew Amazing Fantasy #15, as well as the original Amazing Spider-Man #1- ? Not sure of the number, but it was No. 30 or 40.
According to legend, Stan Lee has long taken credit for the creation of Spider-Man, when in fact Steve Ditko was at least a co-creator.
One artist on the DVD extra disc acknowledged Ditko as his model for drawing Spider-Man, but still, Ditko has been given short shirt. Stan Lee acts like Spider-Man is his baby, but some of us know better.
And what about Ross Andru, an important artist of The Amazing Spider-Man in the late 70s?
