This is a quite nice, original photograph of men sitting on a porch. Written on backside "Matsellton Iowa July 1905" From research that I could do it appears to be the George W Matsell mansion in Linn County Iowa.
The image itself measures 4" x 4.5" and backing matte measures 4 3/8" x 6 5/8"
There is minimal surface, corner & edge wear. Image surface very nice.
A nice addition to any collection!
