This is a magic card sheet, seemingly an advertisement for Shueisha's learning manga series, from approximately 50 years ago. It's a trick where you show the person six cards and ask if the item they're thinking of is on any of them. If it is, you add up the numbers on those cards, and the total matches the item on a corresponding list, creating a surprising "perfect match!" However, it's from the late 1960s to early 1970s (about 50 years ago), so it has a retro feel, with differences from today. The size is approximately 24 cm tall and 18 cm wide. There are some stains, discoloration, and other signs of age, but it's generally in good condition. Please understand this.
