A picture a day to keep the summer doldrums away- 8/10/15

Clint Eastwood pictured with legendary Celtics Bob Cousy, Tom Heinsohn and Frank Ramsey.  Clint's pretty tall, about 6'4 himself.  I wonder if anyone knows the story behind this photo and the reason for the meeting.  Did they play 2 on 2?  Why is he holding a volleyball?

Each day in August, Celticslife will post a Celtics-related picture, one you may possibly have never even seen before.
