Waterfall Painting On Wood / 1971

I sometimes feel like I am drawn to the oddest things when I'm in the wild. I can leave dozens of garments behind and take home a sweet painting on a piece of wood for example :) The back reads "done by Eileen Stehle, July 11-12, '71". Plus, what looks like a phone number. Lovely colors and just the perfect piece to accompany your landscapes! 

condition: good, a simple piece with nailed piece of wire to hang, small hole in the wood (sky area) but this seems to have been present when painted.
