Precious Pictures inside the Original S&M on 3500 South

Our dear friend Debbie Orr found these going through her mother's photographs. Looking at the uniforms and clothing they must be early 1940's, so that would put location as original S & M skating rink at 1810-1820 West 3500 South.
She writes " I wish I knew the names of these great skaters, but nothing is written on the backs. Look close, maybe you'll see your parent or grandparent! "
