"Mt. Rushmore 1940" (Glimpse of Sky and Trees), Mysterious Vintage Square Format Snapshot folk art railroad house I might guess these date

I might guess these date to the 1940s or so and were carved of pine

with old strong tie for hanging

producing kaleidoscopic effects via two painted glass slides

Gorgeous patina to the wood of frame

heavy weight cardboard covered in heavy weight paper

"Mt. Rushmore 1940" (Glimpse of Sky and Trees), Mysterious Vintage Square Format Snapshot folk art railroad house I might guess these dateI like the jarringness of this seeming tear of a view through total blackness with the sky and trees revealed seeming of little consequence, which turns one attention back to the shape of the tear itself. It's the combination of photo with the caption on the back that makes this for me though: Mt Rushmore, 1940. Ha. Perfect. 3 7 8 x 3 7 8 and in good condition, glossy. Light folds to a couple far corners.
