Cheesecake photography gone wrong!  I guess they were posing with ice to avoid the summer heat.  Miss Dorothy Kelly teeing off on a block of ice, c.1925.  The others in the group are Misses Virginia Hunter, Elaine Griggs, Hazel Brown, and Mary Kaminsky.  This is somewhere in the Washington, D.C. area, possibly East Potomac Golf Course, which opened around 1920.
