The Shackleton-Rowett Expedition (1921-22) was the last to be led by Sir Ernest Shackleton. It was sponsored by Mr John Quiller Rowett and ultimately was led by Captain [Commander] Frank Wild. The three were photographed in 1921 looking out from the bridge of the Quest when they paid a visit to Southampton to supervise the fitting out of the ship prior to the expedition. The 45p stamps are based on this photograph in an unusual Triptych format.
The Quest, shown on the 50p stamps leaving London, at Ascension and in Ice, was the smallest ship to ever attempt to penetrate the Antarctic ice.
