What Are They Playing?

   

Well, it's some sort of game though one I'm not familiar with.  There's a game board, a ball, areas with point totals marked.  But the name of the game, I haven't a clue. 

Gyys Drinking

Yes, gyys.  Written on the back, "Gyys off the ship watching the game and drinking beer."  There's even a date stamp, "2.10.71."  So, navy or merchant marine?  What grooming standards did the navy set for it's sailors?  Did they allow beards?  If they didn't we'd know these guys are civilian sailors.
