I purchased this photo on e-Bay and traded it to Larry. The 333 Club was in operation at least as early as 1949 and remained as such until 1953/54 when it became the Copa Club soon under the control of Screw Andrews. This information was pulled from Newport business directories. It was not listed as the 333 Club in the 1944 directory and no records are available for 1945 through 1948.
Therefore, it was the 333 Club as early as 1945 through 1953.
