This poster from 1864 (three years prior to the introduction of the Queensbury Rules) depicts three of the last four bare knuckle boxing champions who were among campaigners trying to organise an official World Championship. From left to right they are; Tom Sayers (champion 1858 – 1860), Jem Mace (champion 1861 – 1862 & 1866 – 1871) and Tom King (champion 1862 – 1863).
