Marx made at least two sizes of cabins for their several playsets. I couldn't get your
photos to enlarge for detail , but that looks to be the smaller one. The larger with a
porch was found in several different ranch sets, in different trims, including the Roy
Rogers ranch set. The smaller one may have been included in some of their fort sets, but I am not sure about that. Marx also made several different farm sets, with different barns, as did Ohio Art, and I can't tell from the photo.....but usually, the litho, if Marx, has their logo on it somewhere.
