A graceful ballerina dances in the moonlight, a snowy swan at her feet, on this lovely pop-up card. With just the touch of a button, a brief snippet of "Dance of the Swans," from Pyotr Tchaikovsky's 1876 ballet Swan Lake, plays. Affix one of the preprinted stickers—choose from "Happy birthday," "Congratulations!," "Bravo!," and blank—in the upper corner of the 6"-tall card, then flip it over to pen your own handwritten message on the back. Budding young ballerinas as well as lifelong lovers of the arts will cherish this pretty missive, which props open with just the push of a tab. Envelope included; extra postage required.
