How do you spot white whooper swans in the snow? Just look for the yellow and black beaks—and listen for the honks, of course. Dutch photographer Jan Smit gives us this lovely image of a mated swan pair. These Sierra Club holiday cards are imprinted with the message "Season's Greetings" inside. The clear-lidded box contains 12 cards, all of the same subject (measuring just under 5 × 7 inches), with 13 white envelopes.
