Knocked a wall down in his studio in order to fit in the canvas that would become Mural (1943), for Peggy Guggenheim's apartment. But he didn't commence work on it until 15 hours before it was due to be delivered - "it was a stampede", he would later report.
When it was delivered, Guggenheim found that it was eight inches too long to fit into the space. On Marcel Duchamp's advise it was chopped down to fit.
More how we work.
