@Danny-Darkoand @Charlie, I remembered seeing this image before and guessed I probably saw it on the Forum. The picture was posted on The Gallery thread called "The Photographer" by @Moondanceback in 2017 and identified as a behind-the scenes shot from the 1931 Finnish film Laveata tietä. It was photographed in the Yrjönkatu Swimming Hall in Helsinki (Yrjönkatu Swimming Hall - Wikipedia).
