Paul Detlefsen - The Smithy - Vintage Turner Wall Accessory

I've seen this called Horse and Buggy Days online as well although I believe that to be incorrect. Print is approximately 23" x 60" inside a solid wooden frame measuring approximately 28" x 64" with a little metal plate indicating the title and artist.   The back of the painting is mostly covered in paper with a few rips in it.  There is what looks like a bit of some type of liquid spotting in a corner underneath the paper, but this seems only cosmetic and not visible.   There is a sticker on the back indicating "This is a Turner Wall Accessory" which might help date it, likely back to the mid 60s. The print and frame themselves are in great shape; there is some scuffing along the side corner of the frame and a little scrape on the print itself, but that's it.  Looking to sell for best offer
