The most pairs of panties ever in an ad.

(click ad, from the 1970s, via) Also, probably the creepiest Mom ever in a panty ad. Look at that expression. Is she a panty-stealing serial killer? Does she take her daughter panty shopping for weeks on end? Did the two of them just raid a Taiwanese panty factory? Is that her daughter? Is Mom wearing any panties? "Sensuous thongs?" In the 70s?
