Guys,

It's been a long time since I took Typography in college but I believe those large pieces are Foundry Type. It's much harder and larger than Monotype. Monotype is small, text sized type that ran on rails in response to the keyboard letter being pressed and when the printing job was done the Monotype was returned to its storage location in the typesetting machine. Each letter had a unique profile that made it possible to mechanically sort. Foundry type was set by hand and was often used in display ads. A professor told us that computer and photo set type was a fad that would pass and hot set type would prevail. I kinda wish he had been right.
