Tommy John has the most famous elbow in sports and now he's using it to benefit charity. According to ESPN's Darren Rovell, John is selling a collage of four autographed MRIs of his rebuild elbow to benefit his "Let's Do It" foundation.

Here's some more, from Rovell:

The images were taken two years ago, when John went to an Indianapolis facility to check on a problem with his shoulder. At that time, the doctor -- out of curiosity -- took pictures of the famous elbow reconstruction.

"Nobody had ever thought of taking pictures of what the nerve looked like on 'Patient Zero,'" said his agent, Kim Berger. "When the images came up, it was like looking at the Titanic. It happened so long ago and it was so beautiful."

The images are signed by John and the late Dr. Frank Jobe, who changed sports history and performed the first ever Tommy John surgery 40 years ago. There were 100 prints made and 99 are for sale at $1,295 each. The remaining print was donated to the Dodgers, who renamed their training facility after Jobe.

John underwent his revolutionary procedure in 1974 at age 31 and won more games after the surgery (164) than he did before (124). Thousands of players have since undergone Tommy John surgery.
