Machines and industrial landscapes: My best flea-market find ever was a set of three black-and-white poster-sized photos of industrial machines I bought for $12 in my hometown of Columbus, Ohio, when I was 19. In a similar genre are images of 1960s supercomputers, which I would collect if I ever came across any. Above is the Elea 9003, Ettore Sottsass’s first design for Olivetti after joining the company in 1957. It reminds me of a patchwork quilt.
