By Various. Comic fan Michael Finn has been going to conventions for years getting '3-minute sketches.' He'll toss an artist a backing board, and ask him to do a sketch in three minutes, no more. The results are often stunning and surprising. Now, The Hero Initiative has collected Michael's sketches into this great art book, featuring contributions from Neal Adams, Howard Chaykin, Steve McNiven, George Perez, John Romita Sr. and Jr., Walter Simonson, Michael Turner and more! See faves like Spider-Man, the Hulk, Hellboy, Wolverine, Conan and more, all benefiting The Hero Initiative! Features an original cover by Joe Quesada!
