Okay, the picture is black and white, so maybe it's not quite clear what we're looking at.
Crunchy ham sandwiches! Buttered white bread layered with ham and process cheese, dipped in eggs, rolled in crushed potato chips, and grilled. I'm half-surprised that no fast food restaurant is offering this on a limited-time basis right now. (Add bacon for 50 cents more!)
At least cooks in the '70s were supposed to serve these with "crisp relishes." (And dessert!)
