The Philadelphia of the 1970s and '80s was the sort of advertising boom town so rich with creative vision that its easy to envision Don Draper, using a family picnic as the backdrop for a Tastykake campaign that touches upon tradition, ritual, and the redemptive nature of the Tandy Take. The ad industry was nothing new to the City of Brotherly Love, of course; in fact, Philadelphian Volney Palmer is credited as being the creator of the first offical ad agency, opening in 1841. But it was during a more recent period in Philly history, when the logos being created for all manner of products were so strong that they continue to have an impact on our day-to-day lives. We've spent most of today searching our memories for recall of what homegrown logos have stuck with us the most, and the results are an overwhelming tribute to the work done by anonymous men and women who once lived and created among us, never getting due credit for the brilliant graphics they have birthed. To those individuals we thank you: This slideshow is dedicated to your tireless efforts towards making Philly commerce into something truly artistic.
