Real photo postcard showing a work crew from the Pittsburgh Wagon Works postmarked October 31, 1910. The original sender wrote on the front, "Some crowd, this'" They were obviously refering to the motley crew on the front. They look like a combination of workmen and mobsters. It's interesting that both the postmark and the written description on the back refer to Pittsburgh as Pittsburg.
Pittsburgh was a big player in the manufacturing of wagons. There was easy access to lumber and iron as well as being a shipping point on the Ohio River.
