Postcards, Greetings Cards and Souvenir Prints This series contains the postcards and greetings cards that have been published by the Museum. DF509/1-177 contain the pre-war cards that were published in sets and sold in a printed envelope with an explanatory leaflet. Cards were published in eight series: A - views; B - mammals; C - birds; D - minerals; E - insects; F - plants; G - fossils; and H - historical. Each set within each series, and then each card within each set, was given an alphanumerical reference, so for example, set E1, 'Representative British Insects', contains cards E1 to E10; E2, 'Remarkable Insect Types', contains E11 to E20. Each set of cards came in a little paper envelope complete with an information leaflet on the specimens depicted. There was also a list compiled every few months, of all the postcards on sale (DF1011/5). The collection of pre-war cards is complete. The collection of post-war cards (DF509/178-255) is incomplete. There are 'duplicate sets' (duplicate note books) relating to DF509/205, 207-210, 213-215, 218-228 1922-2003
