primitive vintage sepia tone paintings, WPA era midwest farm barns

Pair of original oil paintings on canvas board showing barns from the mid west in sepia tones. These are marked with artist's name (R. Shewman) on the back, though they're not signed.

Both pictures measure 18 3/4" x 14", and both are set in rough painted wood frames without glass. Both look like they're in very good shape, though we have to admit to knowing nothing about art.

We just loved these for their subject, the strong lines, the monochromatic colors. The artist was just an amateur, but we think these are beautiful.
