"The artist is by necessity a collector; he accumulates things with the same ardor and curiosity [with which] a boy stuffs his pockets. He borrows from the sea and from the scrap heap; he takes snapshots, makes mental notes, and records impressions on tablecloths and newspapers—why one particular thing and not another, he may not know at the time, but he is omnivorous. He has a taste for children's wall scrawling as appreciative as that for prehistoric cave painting."—Paul Rand, 1955, via Steven Heller
