An outdoor photo, included in the Hoffman photos, so presumably some family members were present:

R.K: A mixed crowd, including, apparently, Poles and Jews. The date falls on a Sunday, so the Poles would be dressed for church. This occasion may be connected with an election coming up in about three weeks. Seated: a lieutenant in Polish military, with additional military men –possibly cavalry– standing behind him. Directly behind him: a police officer. Children in uniform are scouts.
