1984 Tourists Treated Same As Homefolks Enamel Porcelain Sign The Painted Post

Vintage Tourists Treated Same As Homefolks Heavy Enamel Porcelain Made by A Signwork Of The Painted Post, Calliope Co., 1984, Robert A. Bruce. Measures 13" x 7 3/4". There are 3 yellowish streaks running down on it. Not sure what it is, varnish maybe and I didn't try to removed it. Also a small ding in the top corner and some wear around the edges and mounting holes as can be seen in the pics. Overall, a great vintage piece. Thanks For Looking!
