John Severin was exactly the kind of artist I most admire, a rock solid professional who worked and worked and then worked some more. He was immensely skillful and his finishes were like no one else in the industry. I most admire him as a fantastic inker, but his complete artwork was also quite fabulous. I read Cracked for years because it always contained new John Severin artwork.
Rest in peace Mr.Severin.
Here is a very detailed interview with Mr.Severin conducted by The Comics Journal.
