Once, nearly every town had their own local bottling company making flavored soft drinks. Enfield, CT had The Thompsonville Bottling Company, which produced a line of sodas of their own as well as national brands such as Moxie under contract.
In Springfield, MA, the local bottler was Country Club Soda Company, which registered their first trademark in 1908. When I was a kid growing up in the area, we always had a couple of bottles of Country Club in the fridge (especially the ginger ale, which seemed to be my mother's favorite.)
I'm not really sure when Country Club started to get scarce in their hometown. By the early 1980's it was already hard to find. In 1985, Seven-Up bought the company and there were rumors that they were going to take the brand national, but I guess nothing ever came of it.
The only time I ever see Country Club soda these days, it's the occasional bottle that shows up on eBay or at a flea market. Or like in the picture up above: An old cardboard box from the early 1970s. Beat up and filled with junk, tossed in the dirt and debris at the foot of a Salvation Army collection bin.
