Found black tuxedo jacket size 40R with name tag 'John Smith' hanging on a bench near Symphony Hall.

I found a black tuxedo jacket while walking through the park near Symphony Hall in Des Moines last Saturday evening. It was hanging on a bench, and I thought someone might have left it there after an event. The jacket is a size 40R and has a name tag inside that reads 'John Smith'. I’m hoping to return it to its owner!
