Back in the 80s, in Michigan, in almost every grocery store, in the frozen section, there were frozen pizzas that came 2 or 3 in a stack. They had a little white label, they weren't any of the major brands, they weren't even very good. Just 2 or 3 frozen pizzas on a cardboard disk, shrink wrapped. They only ever had 2 or 3 varieties... Cheese, or pepperoni (it was always the little cubed pepperoni), and I think they had a "combo" that was pepperoni sausage and green peppers. I don't know who made them. I don't think it was one company - I think there were different companies that all put out their own version, but they were all pretty much the same. Two or three medium-ish size pizzas, stacked on top of each other, on a cardboard disk.
