The only loaf cheese I have ever seen was the government cheese Ronald Reagan gave away in the early 80’s. I think it was five pound blocks.
We were barley middle class but we weren't poor enough to get it from the government, but my parents bought, or were given, a couple of loafs from family or friends.

My parents bought a cheese slicer similar to the one shown, but it had a roller that kept the slices thin and uniform.
I was only a kid, but from what I remember
that cheese was awesome!!!
It was perfect for omelettes and made great grilled cheese sandwiches!!!
In softness, it was somewhere between Velveeta and American.
