This picture is first cousins Stanley and Osmo Petty, before 1941, in Detroit. Siblings Osmo and Opal Petty went to Detroit to find employment, they heard it was easy to get a job in Detroit. Their first cousin Stanley Petty went with them. I think they had no trouble finding jobs, also no trouble getting into fights. Opal told me Osmo loved to go to bars and get into fights.
