When Robert Rauschenberg’s private collection goes on sale at Gagosian Gallery in New York on November 4, expect everything from modern­ music scores (from friends like John Cage) to the works of early moderns. “Bob was a collagist,” Robert Rauschenberg Foundation curator David White explains, “and his collection came about in the same informal way.” Among the gems: two early Cy Twombly paintings and Jasper Johns’s iconic 1960 Map (above).
