Antique Board and Lodging Sign from along the Lewis and Clark Trail

Possibly 1910 or close. Dayton was established in 1881 and resides amongst the Tucannon, Snake and Touchet Rivers. There's a long history of war between historic residents and newcomers. Some say the streets are haunted and I recently learned there was a primitive prison in the basement of a local establishment. 

There are 9 holes used to mount it around the perimeter. 

Looks to be acid etched and painted (black) on tin sheeting

Measures about 20" x 14" and weighs 14oz

Excellent shape for its age with just a hint of the original paint. It has only been cleaned of its barn dust
