Smash! was a weekly British comic, published in London by Odhams Press Ltd from 64 Long Acre and subsequently by IPC Magazines Ltd from (initially) 189 High Holborn and (latterly) Fleetway House in nearby Farringdon Street. It ran for 257 issues, between 5 February 1966 and 3 April 1971 (although, due to strikes and industrial disputes, publication was not continuous during that period). It then merged into Valiant. The Smash! Annual continued to appear each year until 1975; the final Annual, cover-dated 1976, was published in October 1975.
