The 15¾ x 14½in (40 x 37cm) Merry-Go-Round, a dynamic example of the Grosvenor School draughtsman's linocuts, was one of an edition of 50 dating from c.1930 and signed in pencil. Chosen for the catalogue front-cover illustration, it was estimated at £5000-7000 but sold to a UK private buyer at £26,000 - the highest price seen at auction for a copy of this print and the third highest for any print by Power.

The 2ft 3in x 2ft 7in (69 x 84cm) Adonis in Y fronts, which came to auction exactly a week after Hamilton died, was signed in pencil and numbered 6/40 (there were also a few proofs).

It was produced as part of four early 1960s works on the theme of trends in men's underpants and derived from an advertisement for body-building expanders. The first of many Hamilton screenprints printed by Chris Prater, founder of Kelpra Studio, it sold to a European private buyer at a mid-estimate £23,000.

The Grosvenor School was also represented at CSK when a copy of Sybil Andrew's (1898-1992) linocut The Winch from 1930 went above estimate at £17,000 to a US private buyer.
