Diane Egbert directed me to an eBay auction for an old photo album. She was very interested int eh photo of the interior of the Camp Robinhood Club House. If I hade seen this image I would not have even known that this was from Green Lake unless I noticed the Queen of the Lake sign.
There were a few other cards from Green Lake, and a few that looked kind of like Green Lake, but not really sure. There was a nice selection of the Grotto Shrine at Dickeyville Wisconsin postcards that I will list on my eBay site and recoup some of the expense of the album.
