Coca-cola advertising picture

I acquired a framed Coca-Cola girl picture. The frame is old in itself. The actual picture is 16 5/8" x 10". The framed visible picture is the girl in the pink dress, outdoor scene. I have googled and googled descriptions & image. I was able to find one picture being auctioned but no information. I decided to take the frame apart to see if anything was printed on the back. What I found was the girl in the gold dress and white fur. This is the back side of the outdoor girl picture. I thought maybe a calendar. I did find a 1928 calendar with the girl in the gold dress. But she was facing the opposite direction. Any thoughts would be appreciated.
