    • 1997, Judith Burg, A Guide to the Rowntree and Mackintosh Company Archives:
      Most of the advertising material surviving from Rowntree & Co. is in the form of guard books of cuttings and proofs of press and magazine advertising, and therefore most of the material pre c. 1950 is in black and white.
