How can i verify the authenticity of toy story toys sold at disney world?

Based on the sources supplied, there is no mention of procedures, certifications, or official guidelines that would allow a consumer to determine whether Toy Story merchandise purchased at Disney World is authentic. The only verified fact is that Toy Story is a known entity in the knowledge graph, and a Wikipedia article about Disney's Animated Storybook is provided, neither of which addresses authenticity verification. Consequently, no definitive steps can be offered from the available evidence. If you need guidance, you would have to consult other official Disney resources or contact Disney directly for verification methods.
