The Hero Initiative is starting a fund raiser for retired comic creators. More than 80 artists were asked to participate by drawing a custom sketch on the blank cover of a specially produced Ultimate Spider-Man #100, with 100 total custom covers created. Proceeds from the auctions will benefit the Hero Initiative’s efforts to"provide a financial safety net for yesterdays creators who may need emergency medical aid, financial support for essentials of life and an avenue back into paying work."
Comic Book Resources has a great gallery of all 100 covers on their site. Almost every single one is good (but I can’t quite figure out why Ed McGuiness drew Wolverine and Hulk). A few of my personal favorites are:
But the absolute best one has got to be the John Romita cover.
He was the artist on Amazing Spider-Man from 1966-1970 and his art was the basis for the 1966 Spider-Man cartoon. His son John Romita, Jr. was the artist on Amazing Spider-Man from 1980-1984 and again from 2000-2004.
