Thank you to George Young for contributing this great old image. There used to be a traffic circle on Biscayne Boulevard just to the south of the Sears Tower and Coppertone had a large elevated billboard with this image on it. The bathing suit bottom and dog were motorized so the bottom and dog would move up and down and was visible to all traffic going southbound on Biscayne and around the traffic circle. More people remember the Coppertone billboard at the Golden Glades interchange that was just south of the NW 167th Street exit.

For the record, I believe that Robyn Porter from the Palm Springs section of Hialeah, Florida, was the original model for Coppertone from 1953/54 through 1959 when a very similar ad was recreated in 1959 using a different artist and model. Robyn's father Pete Porter was an artist for the Tally Embry ad agency that received the contract from Coppertone to create the ad and Pete used his daughter Robyn as his model. There is more discussion and comments from people about this matter in the comments section at: http://www.pbase.com/donboyd/memories_ads_old2
