{"product_id":"optical-illusions-playing-card-deck","title":"Optical Illusions Playing Card Deck","description":"There are two ways of seeing things. And sometimes what you think you’re seeing isn’t really there at all. This playing card deck of 55 poker-size cards presents an eye-catching collection of optical illusions that fool the eyes and delight the imagination. Colors, shapes, and appearances transform themselves magically before your eyes. Each card presents a different optical illusion with an explanation of the effect. Many of the optical illusions are famous and familiar including the MacKay Effect and the Muller-Lyer Illusion. Designs in the Optical Illusions Playing Card Deck were created by Pentagram, based on the best-selling books Pentamagic (Simon \u0026amp; Schuster) and Phantasmagrams (Random House).","brand":"U.S. Games Systems Inc.","offers":[{"title":"Default Title","offer_id":42841323602000,"sku":"OPT55","price":9.95,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2974\/3582\/files\/7d52d2c2723a970f03722e1119c2c30af600c5bd8084c256bf9b77b316bd5b37.webp?v=1786388880","url":"https:\/\/store.torontodarts.com\/products\/optical-illusions-playing-card-deck","provider":"Toronto Darts \u0026 Games","version":"1.0","type":"link"}
