This photo appeared in a newspaper clipping sent in by Dave Maas.
 

"This photo was purchased at the Popp Auction in Shawano, 1980.  The owner, Mrs. Koeller, bought it for the frame that it was in.   She thought someone might recognize one of the "sober faced" individuals and be interested in having the photo."

I have no other information about the picture, but if you know who these people are, let me know and I can post their names to this picture.
