The late Elsie Drury, a long time member of BNAPS who attended many conventions and also served as Sales Circuit Manager, was an avid collector of the first set of Postage Due stamps issued by Canada in 1906. Using the draft of a paper prepared by Elsie as a starting point, well known dealer and collector Stan Lum (aka ‘The Yellow Peril’) has applied his extensive knowledge to ensure that Elsie’s work would be included in the literature of BNA philately.Postage Due Stamps of Canada 1906 – 1928, Elsie’s original title retained in her memory, actually covers the first four issues of Canadian Postage Due stamps. The first set was replaced in 1930 when a new printer obtained the contract, again in 1933 when Postage Due stamps were made bilingual, and once more in 1935 when the printer of the first issue got the contract back. The designs of all four issues featured fine engraving, and this style remained in use until a complete redesign was made for the ‘Red Dues’ which were issued in 1967.Included in this volume are print quantities and other information relating to the production of the stamps, as well as illustrations of die and plate proofs, lathework and imprint sheets. Sections on Post Office stationery used with the stamps include Postage Due wrappers, Request for Additional Delivery labels and Dead Letter Office Envelopes. The last part of the book features many fine examples of Postage Due stamps used on cover, the postal history of Postage Dues.
