I don't know why it was in a dumpster, maybe Chris will tell us when I read a little further. 1956 was not a good year for Dean and Jerry. Maybe Jerry tossed it, but it doesn't make sense because Jerry kept everything. Or his heart was just too broken to look at it.
They are both wearing a similar coat, perhaps the same. But Dean with that hat and pipe has a much more "star" look than Jerry who is one step behind Dean as if he has to highlight Dean more than himself. One of the two looks like a real star. The other is a boy who seems to be there by chance. And the gaze turned downwards. Like a shy boy.
In the photo with Jerry Dean he has the old nose. Only a blind person would deny the evidence. Dean and Jerry already knew each other BEFORE Dean's nose job. And the caption of the photo with Jerry says that they OFTEN played baseball. They were friends and hung out A LOT before they became a team. Much earlier.
