From an article by Kon Sokolyk in the "Journal of Sports Philatley", Volume 57, Number 2, Spring 2018.
Invitations to the stamp unveiling (Figure 7) in Regina were mailed in envelopes franked with a “Picture Postage” stamp featuring a red silhouette of the trophy (Figure 6). Two hundred and fifty stamps were printed for this purpose. An additional 750 picture postage stamps were printed for the governing body of junior hockey, the Canadian Hockey League.
