These things happen. They make a small change to a character and a dollar bin book blows up. So please add this book to your weekend back issue bin raids.
Marvel Knights Spiderman #20 has an appearance, a first appearance if you will, of Mary Jane in an Iron Man Armor. News (rumors) has been spreading that Mary Jane Watson Parker would be getting an Iron Man book. Larry Doherty of www.larryscomics.com keeps using the catch term “Spider-Mom” as he said this is what he has been hearing.
Needless to say, Marvel Knights Spiderman #20 has become a hot ticket item and is selling well on eBay.
Mycomicshop.com has some cheap copies left (in F condition).
Also be on the look out for the variant featuring Scarlet Spider on the cover.
