Where were you during the 1967 Detroit Riot?

Scroll down and look at the back of the second one. It says 'Labor Riot June 10, 19[[2)7
Could be [[3)

I'd say 37' since those cars weren't made in 1927. Good call.

That makes sense since the 37' time period was known for the labor strikes in the area, and riots, I suppose.

The other one, could be a protest for the preservation of Bebe creek, which flowed through the park. It was buried underground at some point, perhaps then?
