A reader recently identified the typeface I commented upon in this post as being Ashley Crawford, and not Neuland as I had then speculated. Thank you Marvin.
The face was designed by Ashley Havinden, a noted designer of that period and produced by Monotype as Series 238 and 279 (the later for the plain font). Image from Encyclopaedia of Typefaces, Blandford Press, 1953 as in my copy of Specimens of the Type Faces, Borders, Ornaments, Rules and Other Material cast on ‘Monotype’ Type Composing and Casting Machines, The Monotype Corporation, n.d it is not included, although ‘single specimen sheets…may be obtained on application’.
To correct the earlier misinterpretation here is Neuland used in another ad (taken from The Typography of Newspaper Advertisements, Meynell, F, 1929).
