This is Folly: The Consequences of Indescretion by Hans Rickheit, published by fantagraphics. I followed many of these strips online, as they were being produced. I even commissioned one of the strips myself (it happens to be the one used on the cover).
Get to know the surreal, disturbing, yet addicting world of Hans Rickheit. You won’t be sorry. If you want a huge sampling of his work, go to http://chromefetus.com/page1.html
