Hand-coloured photograph of a portrait of Victoria, Crown Princess of Prussia set within a gilt frame.

Coloured by Lock, the original photograph by William Bambridge shows the newly married Crown Princess walking arm-in-arm with Crown Prince Frederick William of Prussia at Windsor Castle on 29 January 1858 (RCIN 2900125). A payment to 'Mr. Lock of 178 Regent Street' of £6 1s 6d in April 1857 for a 'Painted Photograph mounted of the Ps Royal' was recorded in Miss Skerrett's accounts (RA VIC/Z 276 74), and indicates that Lock had been employed previously for this sort of work.

Samuel Lock was a photographic miniaturist working from studios at 100 (1855) and 178 Regent Street (1856), London, converting calotypes into miniatures. Lock went into partnership with George C. Whitfield as 'Lock and Whitfield' from 1 September 1856 and was much employed thereafter by Queen Victoria and Prince Albert.
