Features of the Publicity FDCs
1. Envelopes : 1960 -66
Canada Post Office replacement FDC envelopes and commericial Rosecraft envelopes were used in the first six years of the programme.
a) Canada Post Office P.S. 2 Envelopes : 1960 - 1963
Initially, 5000 Canada Post Office "P.S. 2" envelopes with a crown cachet were printed for the project. The P.S. 2 envelopes had been used to replace first day covers that were damaged in servicing.
i) January 25, 1960 printing order
P.S. 2 printing order January 25, 1960
ii) November 4, 1960 Printing Order
An additional 10,000 envelopes were printed.
iii) February 16, 1962 Printing Order
The number of envelopes printed was not included
b) Rosecraft Commercial Cachets : 1963 - 1965
From 1963 to 1965, the project used Rosecraft first day cover envelopes supplied by J.C. Rosenbaum instead of Canada Post Office printed envelopes.
i) Rosecraft Issue Specific Cachets : 1963 - 64
The first Roescraft cachets were issue specific envelopes which were used for five issues during the 1963 to 1964 period, beginning with the Frobisher issue on August 21, 1963.
Rosecraft issue specific envelopes used as publicity FDCs
ii) Rosecraft Generic Parliament Buildings Cachet : 1964 -1965
The Rosecraft generic Parliament buildings envelopes were used for 16 issues from 1964 to 1965, beginning with the Maple Leaf Unity Issue, May 14, 1964
The cachet for most issues was black, but red, blue and green cachets were also used.
c) Bilingual Canada Post Office Crossed Flags Cachet : 1965 - 1966
A new Canada Post Office first day cover envelope featuring Canada's Coat of Arms above two crossed Canadian flags was printed and used to publicize the the Christmas stamp issue, October 13, 1965. The crossed flags envelope was used for all 1966 Publicity FDCs.
Letters describing the stamp issue were inserted in the FDCs. The inserts were translated into about a dozen different languages, including Spanish which was used in the Girl Guides FDC insert addressed to Cuba :
Distinctive printed addresses were applied to publicity FDCs and can therefore be used to distinguish publicity FDCs from replacement FDCs as well as identify Post Office publicity Rosecraft envelopes.
(I have relied on Mr. Charles Verge's article in the October 2010 Scott Stamp Monthly Article, Canada's special publicity first-day covers designed for influential people abroad for this section.)
a) Block & Anderson Bandarette Address Labels : 1960 - 1963
The Block and Anderson labels were printed in purple ink with letters at the upper right of the address indicating the language for the insert.
POL indicates that the addressee is to receive the publicity letter translated into Polish
b) Addressograph Address Machine : From 1964
In March, 1964, an addressograph machine was introduced to produce a more permanent addressing system. The labels were printed in black ink.
Wikepedia provides this description of the addressograph machine:
An addressograph machine of the 1960s was essentially a steel frame with an integrated keyboard for stamping out address plates, a cassette-style plate feeder, a heavy-duty, rapidly moving inked ribbon, a platten for hand-feeding the mail piece, and a foot pedal for stamping the address. The individual steel address plates were inserted into card-sized frames which had a series of slots along the top where colored metal flags could also be inserted for sorting purposes. The plate assemblies were placed in steel cassettes resembling library card catalogue drawers, which were manually inserted into the machine. At the press of the foot pedal the plate assemblies were swapped in sequence in a similar fashion to a slide projector, placing an impression of the raised type onto the mail piece.
