One morning the dolls leave the nursery for a drive in their perambulator. The nursery door suddenly opens and the dolls return in their perambulator. A black perambulator was found about a mile away, its cushions soaked with blood. One of his most famous works was 1914's impressionistic orchestral suite "Adventures in a Perambulator". For his own surveys, Colles used a perambulator of his own design and construction.
