Here is another pic from the same day (June 23, 1957), but a different game. It is a very interesting pic as it looks like the two teams are getting ready to brawl. The Reds were playing a doubleheader on this day. The Reds eventually swept the twinbill with a 5-2 victory.

By virtue of the scoreboard, Smokey Burgess is at the plate. After this pic, he hits a home run and Kline is taken out of the game.

The Reds in this pic are Ed Bailey (6), George Crowe (15), and Smokey Burgess (7). The Pirates in this pic are Nellie King (29), Vern Law (32), Roman Mejias (25), and Hank Foiles (20).

Also...in looking at this picture, the billboard above the laundry was Bavarian's Beer which is another piece to the Crosley puzzle.     Reference Here
