OG Acrylic on Canvas Painting River Red Barn Autumn VTG Folk Art Signed Schuster

I'm calling it Acrylic on Canvas b/c I don't see the elevated brush strokes typically seen with oil. I see brush strokes, just not deep ones. I could be totally wrong and it may be oil on canvas. It's definitely a vintage piece, as I see the typical age darkening of the canvas on the sides and back. Measures 16" x 20" (portrait). Signed by the artist "Schuster". Appears clean with no damage. There's a tiny pin hole on the very top edge where a hanging nail may have came thru. It's in the clouds and very unnoticeable. It would be totally hidden by a frame as well.
