When a couple of visitors to the bunkhouse asked if I had any genuine reward posters (there are some on the net that are fun to look at with their pictures and all, but they are recent creations) that I could show them, I was able to rustle up a few good examples of the type of wanted poster that was common during the latter part of the 19th century. (To add a little more authenticity, they are "posted" on an 1880s stable wall.)
Poster put out by the famous Wells, Fargo & Co.
Note that the wanted person's image seldom was on a poster--most folks in the area knew the fugitive already.
