This roundel is a model for the obverse for the Art Union Laudatory medal, and is made by George Gammon Adams. It depicts the head of Sir George Gilbert Scott.

Sir Gilbert Scott (1811-1878) was an architect. He was educated at home and with his uncle. Then he became a pupil of Sir Robert Smirke and afterwards practised both independently and also in partnership with W.B. Moffat. He was much concerned with the Gothic revival. As such he was responsible for the building or restauration of many churches, cathedrals, chapels and public buildings, like workhouses and schools. He also designed for example the Albert Memorial in Hyde Park, the Glasgow University building, St. Pancras Station and Battersea Power Station and Bankside Power Station, now housing Tate Modern.

George Gammon Adams (b. 1821-1898) was a portrait sculptor and medallist. He designed and exhibited prize medals for the Great Exhibition. In 1852 he was chosen to model the death mask of Wellington. One of his public monuments is the 'Napier' statue in Trafalgar square.

The roundel was among the items given to the Museum by I. D. Adams, the daughter of George Gammon Adams, in 1980. In total, 196 items were included in the Adams gift, which consisted of many models for medals as well as the busts and figurative sculpture. In most instances it is not possible to date conclusively the many models included in this gift.
