These photos were in a little yellow photo booklet. There is no date but the developer was “Rockford Photo Service”. It looks like it was a play. Based on the woman with the bobby socks and oxfords in the last photo, these were probably taken in the 1950s.
At first I suspected it was the Moose since my grandparents we active members there, but I zoomed in on the top center of the last photo and it looks like it is a 5-pointed star. I am pretty sure they were not Wiccans.
Wikipedia suggests that the Order of the Eastern Star, a Masonic group open to both women and men, uses a pentagram as a symbol.
I’ll never know what was going on here, but it is fun looking at the photos.
