Absolutely a type 1. Beautiful photo! The follow-through pose, the outfield wall background and great balance make this one pop.

The matted slug most likely isn't original. It looks like it was created later as a descriptive companion piece to the photo. The slug attached to the photo looks good though. The stamping is also period and good.

It looks like the grey editor's ink or mask around Joe can be removed. Most of the time the ink used is water soluble and will lift easily using a damp paper towel. I have removed ink on many old photos and they turned out great. Removing the ink will not hurt the value or desirability. Be careful to not saturated the surface of the photo. Use just enough moisture to loosen the ink. Also, use an easy wiping action with light pressure. If you do choose to remove the ink, please show the results. Super photo.
