Two rosy-cheeked cartoon children — a grinning boy with a satchel and a wide-eyed girl in polka dots — pedal their red bicycles past a wooden signpost reading "LAUSANNE OUCHY," their cheerful encounter framing one of mid-century Swiss tourism's most charming conceits: behind the signpost panel, a hidden leporello accordion strip of eight miniature black-and-white photographs unfolds to reveal Ouchy's lakeside harbour, the Grand-Pont, the cathedral skyline, and panoramic views across Lac Léman to the French Alps. These novelty "pull-out" cards, popular throughout Europe from the 1930s to 1960s, were designed to pack maximum souvenir value into a single mailing — the recipient got both a whimsical illustrated greeting and a pocket-sized photo album of the destination. The phrase "Salut bébé… Ça roule?" ("Hey baby… How's it rolling?") is a playful French cycling pun that gives the card irresistible personality. The accordion strip remains fully intact and clean.
