Inside Sam's office there is a black and white photo by the door. Looks to be two boxers holding a baby. Who are they?
It appears to be a photo of two boxers : Max Baer and Primo Carnera, probably around when they had a match in 1934.
Why Sam would have it in his office is anyone's guess.
Edit to add: Although a clue might be that perhaps the child is Max Baer jr .... who later became a comedic actor on The Beverly HillBillies !
