Miss or Madame Barclay by Lock & Whitfield, July 1864
Lock & Whitfield (active 1856-1894).
Samuel Lock was an artist who in the early 1850s was converting talbotype portraits into painted miniatures. In September 1856, he joined forces with George Whitfield, who had recently opened a photographic portrait studio on Regent Street in London. The firm established a branch studio on Kings Road, Brighton in 1864 and are best remembered for the series of woodbury type portraits published in Men of Mark.
