Here's a nice little cabinet photo featuring a group of workers from Missouri. The piece is unidentified, but has a photographer's mark at the lower right from Hornbeck's Studio in La Plata, Missouri. I tried to figure out what the sign says over the worker on the top left, but couldn't make it out even when I rescanned the photo at a higher resolution. I'm not really sure what type of work crew this is. They're sitting on a flatbed rail car and some of the guys are wearing rubber gloves and boots.
