How to verify disney merchandise authenticity and exclusivity?

The only evidence supplied concerns Disney's Animated Storybook, a point-and-click adventure video game series released in the 1990s. It describes the game's development, platform releases, target age group, and voice talent, but contains no mention of merchandise, authenticity verification, or exclusivity. Therefore, based on the verified source, no guidance can be given on how to authenticate Disney merchandise. Users seeking such information should consult official Disney channels or reputable retailers for authenticity checks.
