The first photo below is the photo of Lefty from eBay.
The second photo is a picture of Connie Mack and his son Earle from 1925. This shows a Philadelphia Athletics uniform from 1925 along with a sweater/jacket that appears to be the same as what Lefty is wearing in the eBay photo.
You can find this picture at the link below, which indicates that this picture was taken in 1925.
