Above de Cardenas’s bed is a Czech block set from the ’50s that he bought at the flea market in Fort Greene, Brooklyn, then framed. “The blocks on the right came in that box — that’s the cover right next to them — and the other four images are examples of how you could configure them,” he explains. “I had a bigger idea for this. I originally wanted to make these four designs out of the blocks and photograph each one, then put the images underneath the instructions, but it didn’t happen. It was my homage to a client of mine’s parents, who are huge art collectors. They had a console table with Rembrandt prints hung above it, really low, and beneath each was the metal plate it was printed from. This is my version of that.”
