A collaboration between Ed Ruscha and Billy Al Bengston from 1968, Business Cards wittily documents a business card exchange project, starting with the artists designing the cards and ending with a ceremonial exchange at the Bistro restaurant in Beverly Hills. Limited to one thousand unique copies, the volume features a black-and-white photograph adhered to the wood-grained Bristol board cover with photo corners and is bound with a knotted leather cord. The artists’ business cards are stapled to the final pages of the book.
