Two chubby, wide-eyed children in bright red and blue bathing suits push and pull at an enormous beach ball in the shallows of a lake — but this charming "Gruss aus Zell am See" (Greetings from Zell am See, Austria) card conceals a delightful secret: the beach ball is actually a paper mechanical device that opens like a clamshell to reveal a folded accordion of miniature souvenir photographs of the alpine lakeside resort. The German verse beneath reads "Im Wellenspiel den Ball wir drehen / und ließen Dir schöne Bilder sehen" — "In the play of the waves we spin the ball / and let you see beautiful pictures" — a perfect description of the novelty's function. Zell am See, nestled in the Salzburg Alps beside the Zeller See, was already a fashionable summer and winter resort by the Edwardian era. The card is a quintessential example of the elaborate German novelty postcard tradition, produced for the tourist souvenir trade. The miniature accordion booklet of resort views is partially visible in the detail image, still tucked within the opened ball compartment.
