How can i verify the authenticity of a disney toy story toy?

I do not have any evidence or data about methods, documentation, or official sources that can confirm whether a Disney Toy Story toy is authentic. The provided sources discuss Disney’s Animated Storybook video games, not toy manufacturing or authenticity verification. Because there is no verified content addressing this question, I cannot offer guidance or specific steps. For reliable authentication, consult official Disney or Pixar resources or reputable collectors’ guides, but that advice is outside the scope of the provided evidence.
