It turned out that the combination could work well in the Guggenheim's space, but, Messer recalled that at the time, "I was scared. I half felt that this would be my last exhibition." Messer had the foresight to prepare by staging a smaller sculpture exhibition the previous year, in which he discovered how to compensate for the space's weird geometry by constructing special plinths at a particular angle, so the pieces were not at a true vertical yet appeared to be so. In the earlier sculpture show, this trick proved impossible for one piece, an Alexander Calder mobile whose wire inevitably hung at a true plumb vertical, "suggesting hallucination" in the disorienting context of the tilted floor.
