How can i verify the authenticity of disney park exclusive toy story merchandise?

The only verified information supplied is that Toy Story is a known entity and that Disney produced an interactive storybook game series in the 1990s. No details are given about Disney parks, exclusive merchandise, or authentication procedures. Because the evidence does not address the question, a specific method for verifying authenticity cannot be derived from these sources. In general, authenticity checks for merchandise typically involve official packaging, serial numbers, holograms, or retailer documentation, but these details are not present in the provided evidence. Therefore, based solely on the verified information, a definitive answer cannot be provided.
