Are there any toy story fan conventions with exclusive merchandise?

The only verified entity in the evidence set is the Toy Story film franchise; none of the sources mention fan conventions or exclusive merchandise associated with it. The Wikipedia excerpt provided relates solely to the Disney Princess franchise and does not address Toy Story or its merchandising. Because fan conventions are not referenced in the available data, we cannot confirm the existence of any such events. While it is common for fan gatherings to feature exclusive items, without a direct source we must treat this claim as unsupported. Therefore, based on the current evidence, there is no confirmation that Toy Story fan conventions with exclusive merchandise exist.
