According to the person that took these pics, he has advised that they are from May 8, 1955 which was a doubleheader with the Cubs. I had been leaning towards the Cubs based on the scoreboard but it was difficult to determine.

The date of May 8, 1955 seems to work. The pitcher in this pic is Steve Ridzik who only started two games for the Reds. His uniform number was 33. The game is in the top of the third inning. The Cubs eventually scored one run in this inning. I am working on the remaining players.
