Watercolor painting of some age, 13" by 10 1/2" (22" by 18" framed), the subject simply a tree, but, that subject is handled very beautifully, and the work is signed at lower right by artist Paula Day (on whom I find no information). The interpretation of light and color belies the hand of a talented artist. Judging from the framing materials this dates no later than the mid 1960's and likely earlier. I recommend a new mat only; the frame can be retained.
