The ad announcing the Grand Opening of the Clark Super 100 Station at 1999 Cooper-Foster Park Road in Amherst appeared in the Journal on July 15, 1971.
I like the ad. It creates a spirit of fun and excitement, with lots of freebies (glasses, balloons, suckers), an appearance by Bobo the Clown (hopefully not the one at the dunk tank at the Ohio State Fair) and a nice photo of James Manser, the Clark dealer in charge.
Back in the 1970s, Clark was one of the biggest independent oil refiners and marketers, even as it competed with the major brands of gasoline (such as Sohio, Sunoco, Texaco, etc.) that spent a lot of money on advertising.
But while many major brands have simply gone away or abandoned Ohio entirely, Clark is still around. You can find stations in Cleveland, as well as smaller rural communities such as Shelby and Fostoria.
