"John K. Crellin notes that 'While the history of advertising medicines in Britain has attracted much interest, the prescription
envelope has rarely been noted. It has attracted interest as ephemera, for which see "The Chemist and his Stationery. The
Prescription Envelope, the Label and the Letterhead" in: Chemist and Druggist 159 (1953): 603-606 [unsigned, but presumably
by Arthur Wright, owner of a large collection of Prescription Envelopes]. The article notes that the envelope continued after
the advent of the National Health Service in 1948, albeit in smaller numbers for private prescriptions The article bemoans
the loss of "typographical or design interest" and that as "an 'art form' if they could be called that, prescription envelopes
maybe considered dead.' Source "The Humble Prescription Envelope in the British Medical/Pharmaceutical Marketplace" in: Pharmacy
in History, Vol. 49, No. 4 (2007), pp. 131-138. In 2002 the Wellcome Library exhibited: "The chemist's shop: advertising from
shops and advertising for shops from 1860-1945." For further references see also William Helfand's review of "Receptkuverter"
