From Mick Melvin:
This ghost sign is on the side of the Red Rock Tavern on Capitol Avenue in Hartford, CT. According to the bar's web site, the tavern has changed names a few times over the years, but has been in business for more than 80 years.
Red Rock Cola was a product of the Red Rock Company, which was established in Atlanta in 1885. The first beverage the company distributed was actually ginger ale, according to the web site for beverage distributor Pipeline Brands. Red Rock produced Afri-Cola for many years in the early 20th century as well, according to the CokeGirl web site.
Red Rock experimented with many other flavors over the years, but it wasn't until 1938 that Red Rock Cola hit the market, according to Pipeline Brands.
Red Rock Cola was the only soft drink endorsed by Babe Ruth, which he did in 1938. The cola was distributed in most of the US, but sales declined in the late 1950's. The company soon disappeared in the states and little is known about the circumstances.
Fortunately, the formula was preserved and the cola was produced in the Dominican Republic by the Cerveceria Nacional Dominicana. Red Rock has been distributed in many countries in Latin America, including Venezuela, Panama, Trinidad, Puerto Rico and Cuba.
The soft drink was reintroduced to the states in the 1980's in Alabama and has since established distribution centers in Georgia. The Georgia center distributes the beverage to Colorado, Oklahoma and Utah. The beverage can also be purchased online.
I'm not sure if you can get a Red Rock Cola at the Red Rock Tavern in Hartford, but I'll let you know on my next visit.
