The Hostess brand of snack cakes includes Twinkies, Ding Dongs, Ho Hos, and an assortment of other sweet confections. In the 1970s, it commissioned comic book stories in DC and Marvel publications promoting its products. In these classic ads, several of which you can view here, Captain America, Batman, and other heroes endorse Hostess cakes and good behavior.
Comic Book Resources has a regular feature called The Line It Is Drawn which challenges comic book artists to make funny images along a central theme. This time, it was modern versions of these classic Hostess ads. You can view them all here. My favorite is the rough Marv from Sin City selling Twinkies, courtesy of artist Nick Perks. It references a miniseries in the Sin City universe called That Yellow Bastard.
