My original tumblr post was here. This image was researched by Bacchus at ErosBlog as part of the “Δ commission.” The research was originally published at Hedonix as “Δ 029 Captain Obvious Is Obvious.” Here is what Bacchus found.
This comic art was created in 2010 by artist Joshua Kemble (whose official site here has quite a large portfolio) for a tee-shirt contest, according to the artist’s BlogSpot blog:
Nathan Stillie (aka Ndstillie) came up with this fantastic concept, and I executed it, figuring it would make a perfect third submission to the Loves Comics Contest, this one being a parody of the super hero genre of comic, featuring captain obvious, and his obvious ways of pointing out… well, the obvious. Obviously. For a long time I’ve believed comics would make awesome shirts, and am glad to participate in the loves competition. Hope you guys like it!
Thank you, Captain Obvious! Shirts and art prints of this artwork remain available.
