The artist signature appears to be (Withers). I have found signatures from Ted Withers and the one on this painting appears to be the same. American pin up art. 1896-1964. Last picture is of his signature found on line. Shipped with USPS Media Mail. Has damage (bubbling/cracking) Art needs to be repaired and cleaned. Please look at the pictures carefully. What you see is what you get.
