From the fall of 1952 to the spring of 1953 Rauschenberg traveled through Europe and North Africa with his fellow artist and partner Cy Twombly. In Morocco, he created collages and boxes out of trash. He took them back to Italy and exhibited them at galleries in Rome and Florence. A lot of them sold; those that did not he threw into the river Arno. From his stay, 38 collages survived. In a famously cited incident of 1953, Rauschenberg erased a drawing by de Kooning, which he obtained from his colleague for the express purpose of erasing it as an artistic statement. The result is titled Erased de Kooning Drawing.
