Went on a wild good chase trying to find the "Secret origin of Supervillains #14" mentioned in an editor's note - turns out the issue it's referring to DC Super Stars #14 - one of the books where every issue is essentially an unrelated one shot but the indicia carries an issue number for the overall series. Anyay, the two-face story in there was fine - the most interesting thing about it to me was that it confirmed the first time Two Face got plastic surgery to cure himself was still canon, so it's very funny that this story has him do it again (and implies in the end that he'll do it a third time) - but then the flashbacks to Two Face's origin in this issue contract the other one, as this one is very faithful to the original golden age origin, oh well. Loved the ending, hopefully it sticks for a little bit (I know it doesn't stick post crises, but I just hope that the next time two Face pops up they don't completely ignore this story), and Mike W. Barr's backup was fun!
