Notes:
Marv Wolfman recalled the following about MAYHEM IN MANHATTAN: "Pocket Books asked us to write the first Spider-Man novel in something like 30 days. If I recall, I wrote the first draft and Len the second, which was the only way it was possible to do." (quoted from a 9/2009 posting on Kupperberg's blog, Capes, Cowls & Costumes at bookgasm.com).
