Do disney parks provide authenticity certificates for their exclusive toy story?

The provided sources do not mention any Disney park policy or practice regarding authenticity certificates for Toy Story items or any other exclusive merchandise. A search of the available evidence shows only the general existence of the Toy Story franchise and details about the TV series Bluey, but no reference to authentication documents issued by Disney parks. Therefore, based on the verified information at hand, it cannot be confirmed that Disney parks provide authenticity certificates for exclusive Toy Story products. If an authenticity certificate exists, it is not documented in the sources provided and would require additional reliable confirmation.
