Odd Local Reproductions Of 1863 $1 Note -- Any Info?

I've found a set of several 1863 one dollar reproductions that have little sketches on the back of local buildings from Lebanon, Missouri -- that's where I lived in 1976 but I was a little kid so I don't know where these came from. The backs of the repros say "America's Bicentennial 1776 - 1976 -- Lebanon -- A Bicentennial City." I can find nothing about these online. Has anyone seen these before? I assume multiple cities had these back in 1976.

Here are some photos. The fronts look the same in all of these, and the backs each have a different building. This one is the "original courthouse."





Any thoughts? Thanks!
