Large landscape painting (oil i would guess) that is approxitely 96" by 48" that has been painted on a textured board, i've heard the word "canvas board" used before.
It appears to be Grand Lake, Colorado and features a resort scene in the foreground and a mountain range in the background. The painting is signed in the lower right Elsie C. Patty 1956. What little information i was able to find was that Patty was a artist in Colorado and may have had a studio at one time in the Grand Lake area. I've seen a few smaller paintings done by her but nothing near this size.
Wish I could say more about it to help but no very little about painting technique or materials to provide more information than I have already. Thank You!!!
