Early 20th century vintage portrait photo, a baby in a long white dress. The frame is period to the picture, a tiger grained oval with domed convex glass 'bubble'. This measures 19" x 13" over the glass, 21" x 14 1/2" over the wood frame.
It's showing it's age - a little discoloration to the photo, some wear and scuffing to the frame. The glass looks old too, but has no condition problems that we could see.
