I've become familiar with Matt when I got a copy of Super Spy from Top Shelf Productions. While he's been writing on more mainstream titles as of late, it's his unique artistic style that drew me to him. I met him in Baltimore in 2008, where he drew the first Nite Owl from Watchmen.
Less than a year later, I hit him up at MoCCA Arts Festival for Bane. Shortly after that, I got the First Doctor from Doctor Who at Comic-Con International.
The last time I enlisted Matt was at Big Apple Con in 2011. I came to him with a blank-covered Wolverine #1 and references from the popular "Old Man Logan" storyline. Matt churned out an awesome dystopic take on the character.
HONORABLE MENTIONS: Joe Kelly (four sketches; he'll probably kill me for including him, but he's got a little artistic skill for a writer), Ryan Kelly (two), Barry Kitson (one sketch of Superman from Kingdom Come that has a story to it), Michael Kupperman (six; four from his amusing Tales Designed To Thrizzle series).
