This set of six unused cards without any pre-printed postage was issued by Hongkong Post in 2021 to celebrate the Centenary of the Society for the Prevention of Cruelty to Animals (Hong Kong).   Our scan shows one card (dog) while other cards have a cat; what might be a tortoise; a rabbit; a bird; and some indeterminate animal that sort of has the face of a camel and the body of a bear.  They’re all in party mode, as we will be if you buy this set!  Grade: 1
