I have 2 copies of a bumper sticker which was recalled! It seems that during the gas crisis of the 70's, the EPA (Environmental Protection Society) decided to promote the 55 MPH spped limit with some funny bumper stickers.....one which was printed and put out in the lobby, but HURRIEDLY packed up and destroyed read---(I got a couple because I knew someone..)

"Driving 55 is chic..driving 75 is Sheik"
