Oil Painting Of Two Ducks On Table

I found this painting at a thrift store today. Actually I saw it there last week, but I bought it today. It only cost $1.98. The price was written in grease pen on the front in the upper left corner (gggrrrrr). I managed to rub it off with a rag. If you look close up you can still see where it was. This painting is old, or made to look old. Not sure. It is an oil painting and there are small cracks in the paint as if it were old. The painting is on thin board, I think plywood. The painting is of two ducks as if brought home from a duck hunt and left on a wood table. For $2, I took a chance on it. It seems old. It measure 18.5″ x 24.5″. There is no signature. The back is just painted black. There seems to be a shadow of a ducks head just below the lower ducks head. Is this a painted shadow, or did the artist move the head? Anyway, they are dead ducks.
