I don't know if this would be your Michael or not - although I tend to think not. There is also an address on the back that says 833 Junction Ave. I am wondering if this would not be in Detroit. The line under the address is " 1 Pin ( the P is questionable, could be C) - No 50. I have no idea what that is. The name Gunning or Staup may be related to the Werling family as I have no idea which family this picture came from.
