Presumably the same picnic as the other similar photo, but this time the lads are a bit more in shot, and the girls (Nora and friend, in summer dresses) are more in their hostess and guest roles. And perhaps that’s WGRA’s sister Rose in the background, enjoying a sandwich. This is from the Archer family album. Which also includes Eileen and sister Pamn in the early-to-mid 1930s. Lots of interpretable information for those who can read it: attire/attitudes/expressions/accoutrements/etc.
