Large signed framed Mallard Duck painting Unique

Large Signed Framed Mallard Duck Painting on Stretched Fabric This is a large wooden framed and signed Mallard duck painting on stretched fabric. It has been professionally matted and framed. The painting measures 13 1/2" x 19", the frame is 21 1/2" x 25 1/2". The painting is whimsical, bold and bright in colors found in nature. I am unable to tell if it is acrylic or oil as the back of the painting is wrapped and I don't want to disturb the framing. The signature is either L. Wilson or d. Wilson. The painting is in pristine condition. The only flaws are a chip on the top of the frame and a chip on the bottom of the frame (see photos). The painting is under glass so there was glare when photos were taken.
