Bluebird painting framed stretched canvas

This charming bluebird painting is on stretched canvas and is signed by the artist. Framed. Approximate measurements are 11" tall and 8.5" wide. There is a faint small shadow on the left side. Please examine the photos closely as they are part of the description. I bought this item at a house sale and no one could tell me how old it is or where it's from. It will add a touch of vintage charm wherever it's displayed.
