Writer Sean T. Collins not only wrote one of the most gripping David Bowie comics ever, he also turns out to be a major collector of Bowie themed cartoonist art. Collected at festivals between 2008 and 2010, the gallery features some 103 sketches, cartoons and portraits by luminaries ranging from Farel Dalrymple to Scott C, any of the Hernandez Bros, Jason, Kate Beaton and (my favorite) Kevin Huizenga (above).
In 2009 Collins did a write-up for Robot 6 about the background of the collection, with plenty of anecdotes about the various artists.
