Pre-owned and used. Vintage piece. Age unknown.. The is a picture of a letter on the ad that is from 1917 so I know it is later than that..but unknown by how much. See photos for assessment of this fold out advertising brochure. There is edge and corner wear. Also some signs of stress in the fold creases.

** I also tried to research the company to get some kind of grasp on the history of it but there wasn't much that was found with a simple search.
