Excited to add this group to the collection as paper items don’t have a high survival rate. These items would have come with a home movie projector. Date range is currently unknown. Likely pre-war as Keystone started to move away from projectors for kids after the war. The usher arm band would not survive more than a use or two so is rare to see. The tickets could be used multiple times as well as the pin back. The ticket taker badge has no way to attach to anything so I assume it was intended to be shown to collect the tickets.
From my private collection.
