A subway-riders' special: Cheap ad

Currently on display in New York City subway cars are advertisements for a certain over-the-counter cold medication. The ads consist of photos of three red-nosed women, obviously supposed to be suffering from a cold, with captions including such, ahem, stirring words as, "Press on, good lady" and "Soldier on, brave soul." But look closely--the short-haired woman, the woman with shoulder-length hair in ringlets, and the woman with smooth shoulder-length hair are all the same model, in three different wigs. Recycling at its best. :)
