This is a lovely vintage print by the American artist Maxfield Parrish (1870-1966). This one is shown on page 49 in the Erwin Flacks Identification and Price Guide as titled Pandora's Box. It was done originally in 1909 for the book "A Wonder Book and Tanglewood Tales" in the 9" by 11" size, published by P.F. Collier & Son.
It shows Pandora, a lovely dark haired lady, sitting by a box. Her story is from Greek mythology. The Greek god Zeus sent Pandora down to earth with a box that was not to be opened, as it contained all the evils of the world. She stole the key to the box and opened it and all the evils flew out, except for hope which was still left in the box. Today we still use the phrase Pandora's Box when something innocent turns out to have bad consequences.
She is housed in a wood frame that has been repainted a gold color at some point. It has glass, a torn dust cover, with a wire for hanging.
