Footage appears to be of a company party during the '50s in Michigan. 

Four men play horseshoes at an outdoor party or gathering. Medium shot of a woman getting a beer while holding a cigarette. A man grabs a beer and then takes a sip, looking in the distance, as three kids linger nearby. Adults sit at a picnic table, chat, and relax. Lots of people are seen in the background and milling about. A couple sits at a picnic table; the man is holding a beer. A father, who wears a t-shirt that says "G.M. Research, Automotive Engines,"  holds his child, who is wearing blue swimming goggles.
