These are some original mock-ups of Cuban posters; painted on boards and then sent to the printers to have the shapes cut out and separated into colors for silk screening. It’s amazing to see how much the printing industry has changed. It seems that back then the printer had a more of a role in the composition itself, defining the edges and choosing the colors. I can’t imagine dropping off a painting at a modern print shop and expecting them to deliver a silkscreened masterpiece based on it.
