Peg is one of those DC characters who lurked in the interstices for years, starring in a half- or one-page gag every couple of issues. She's a typical blonde teen girl who occupies a world in which all of the females under a certain age have either one giant tooth or a portal to a realm of pure radiance situated in the middle of their faces.
This comic is of course completely mystifying to one such as myself who hates and fears the awesome cancer-spewing might of the sun, but I suspect that the saga of a girl who sets out to get a sun burn in time for the big dance and then can't go to the big dance because of her sun burn might have been a head-scretcher in even the most heliophilic of eras.
