Judging from the look of the Pepsi can (because at a certain age, he changed his soda preference to Tab), this has to be the early 80s. Meals included stories, jokes, animal noises (esp piq squeals), green pea fights at the table, and Nettie (Pete's mom) screaming at us all to stop throwing things (all while she laughed and Peter made fun of her).
I loved eating there on Wednesdays. There were at least 10 family members eating dinner together. Then the great-aunts would go play cards or have dessert at Uncle George's house, and Peter would be in charge of the rest of us. He'd turn off the lights and announce, "OK, it's time for Hide n Go Seek in the dark" and we'd all run through the house screaming.
