Question for those who lived in Cincinnati during the 1960s.....does anyone remember a billboard for Parkway Auto Wash on I-75, just before it merged with Central Parkway, which featured a cartoon of a girl lying on her side wearing a bathing suit which later, during the winter months, became a snowsuit? The billboard read "Parkway Auto Wash around the curve." I'm looking for a picture of that billboard which ran on the front page of The Cincinnati Post if anyone can help me or suggest a place I can go to find it. I already researched this at the Cincinnati Library and had no luck. Any suggestions would be much appreciated! Thanks!
