I must have overlooked this nice display of Canadian Special Delivery stamps on previous excursions into the SCF database. I'm giving it a bump in hopes that Ziggy will correct the title's spelling mistake and to pass on the following excerpt from the initial volume of the BNAPS Topics journal (March 1944. Vol.1, No.1) in which Walter Pollock praised the first stamp shown, namely, the 1898 10c Canada Scott#E1.

My Scott catalogue is old but the others look like the 1922 Canada Scott#E2, the 1930 Canada Scott#E4, the 1935 Scott#E6 and the 1946 Canada Scott#E11 Peace Issue.
