Production File for the 1951 3c Robert Borden Issue, an amazing original group containing many items used in the production of the stamp, with a photograph, two reduced (stamp size) photographs, one destined for the engraver William Ford, two negative images of the issued stamp (one large and one small) as well as a beautiful and rare large die proof, in colour of issue, with several signatures and notes front and back, measuring 152 x 229 mm. We also note 19 letters (Feb. to Apr. 1951) pertaining to the preparation of this stamp, each giving interesting and important information on the various stages involved, as well as the original two government-style large envelopes, each having once contained all or these items, which are itemized in a list on their covers. Last, but not least are three stamp-size original photographs (listed on the cover of one of the large envelopes) each depicting King George VI wearing his military medals, with the names of two engravers, probably in preparation for the series of stamps issued around the same time, but depicting him wearing a suit and tie. A unique ensemble of items, the like of which is rarely offered. (Image)
