I think I've seen some discussion as to whether or not this is a photo of Joe Jackson sliding. It appears on a vintage baseball card that does not cite his name. Here's a link to the photo, with description (the caption reads "April 23, 1915 League Park, Cleveland Jimmy Austin is playing 3rd base Geroge Hildebrand is umpire").
