A wooden concave four-hole button from the 1845 British Northwest Passage Expedition led by Sir John Franklin.

The wooden button was found by Lieutenant William R. Hobson's sledge team on 24 May 1859 at a place where a ship's boat was discovered on the coast of Erebus Bay, King William Island, as part of the search expedition led by Captain F. L. McClintock. Hobson described finding a lot of material in the boat, but does not specifically mention the button [Stenton, 'Arctic' v.69, No. 4, p. 518]. McClintock visited the site on 30 May and records that there was a 'vast quantity of tattered clothing was lying in her' and in the list at the end states 'a wooden button'. [McClintock, Voyage of the Fox (1859), pages 290 and 366].

The button was displayed at the Royal Naval Museum, Greenwich, in Case 2, No. 49. 'Button'. The item is shown in 'Stereoscopic slides of the relics of Sir John Franklin's Expedition' photographed by Lieutenant Cheyne RN, at the United Services Museum, Whitehall, No. 7 (centre, middle).
