Some pieces in "Sinister Pop, " such as Lee Bontecou's wall sculpture of welded steel, wire and rope from 1961, would not look alien in a show about the New York School.
Banded with steel and coiled with thick rope at the ends, the Oak weighed four hundred and fifty-nine pounds it took five large men to carry it onstage.
Mr Kelly told reporters after inspecting it that a length of rope was looped around the piece of steel and that no marks were visible on the walls overhead.
