Hi Donald. Thanks for reaching out! The stamps used on the OFDC are taken from the booklet, which has two mirrored arrangements of the four stamps. So as not to waste booklets, both “mirrored” sides of the booklet stamps are affixed to OFDCs creating two different versions- one with the black bear and Kermode on the left, the polar and grizzly on the right and another one with polar and grizzly on the left, the black bear and Kermode on the right. for Canada Post!
