So here we have the other part of the Advertisement Cards, and there are collectors who believe, quite firmly, that the two are not to be grouped together and to be completely separate issues. They base this on all manner of reasons, including the fact that the four pipe smokers are vertical cards, art drawn, in colour, on a plain white background, whilst the four packings are horizontal cards, from photos, in black and white, presented inside a decorative frame.
However in our original World Tobacco Issues Index they are catalogued, equally firmly, together, as :
ADVERTISEMENT CARDS (A) Sm. Unnd. See Ha.533
1. Packings (4)
2. Smokers (4)
They remain together in the updated version, but that deletes the handbook reference and replaces it with RB.113/401, which is the modern Godfrey Phillips reference book. So if anyone would like to scan that for me, I will extract the knowledge and add it in.
