We have a beautiful framed old picture that has been in my husband's family for many many years -probably at least the 1930's. It is about 38" x 28" and is a picture of two young women dressed in long lovely gowns. One is sitting and playing the mandolin (?) and the other is standing next to her. In the background is another room (a step up) with a beautiful piano in the corner. I believe it is stamped #2430. I would so appreciate any information on this picture. Thank you so much
