Hey everyone. My grandfather recently passed and we've been clearing out the house to sell it for my grandmother. We found this autographed basketball in my grandparents attic.

It's from the 76ers. There are either 13 or 14 autographs. There is one that I can't tell if it is one long auto or 2 separate.

As of now, I know these for sure:

Julius Erving
Mike Dunleavy
Doug Collins
Darryl Dawkins
Pat Williams
Gene Shue

My best guess is this is from the 1976-77 season as that was the only year all of these guys were together. Shue only lasted 6 games the next season so I can't see it being then. I'm going to post all of the autographs so any help with them would be awesome. I know the picture quality along with the deterioration of the ball and autographs makes it pretty tough so no worries if you can't make them out. I just don't really know much as far as basketball goes. Thanks in advance!
