This is a photo taken by Twitter user Dave Howlett of Action Comics #959 featuring a Superman vs Doomsday Snickers ad in the middle of a comic where Superman and Doomsday are actually fighting. Apparently at first it seemed like it was part of the comic. Now that is some serious product placement. That said, for $100 I'll casually slide the name of your business into a Geekologie article Bill's Pool Supplies. See? So discrete it was practically subliminal.
Keep going for just a shot of the two panels.
Thanks to Kim, who agrees there's clearly some sort of FCC law or regulation being broke here.
