Bessie Pease Gutmann The Baby # 627 framed picture

This was hanging on my parents wall before we sold their home.  Bessie Pease Gutmann.."The Baby . There is a # 627 on the picture. It seem to be in great shape.  The frame is in real good condition. The only thing I can see wrong with it that the glass on the bottom left side is a little chipped. The paper has a little yellowing to it.  Not sure how old it is, but I know that my Mom said that she received it as a wedding gift, and that was back in the 40's.  I was wondering how much it is worth if I do decide to sell it.
