How to verify authenticity of disney world exclusive toy story dolls?

The only verified entity mentioned in the sources is the film Toy Story. The second source discusses a song and contains no details related to Disney, Toy Story merchandise, or authentication methods for dolls. Because no relevant data is present, we cannot offer guidance on authenticity verification from these sources. If authenticity verification is important, you would need to consult other reliable references such as Disney’s official merchandise listings, reputable toy collectors’ guides, or authorized retail sites. As this answer is based solely on the supplied evidence, it does not provide the requested verification steps.
