When did disney launch its first exclusive toy story merchandise?

None of the evidence supplied includes a date or description of Disney’s first exclusive merchandise related to the Toy Story franchise. The Wikipedia entry focuses on the character Woody and his creators, and the knowledge graph only confirms the existence of the Toy Story entity. Because there is no mention of a merchandise launch, we cannot provide a specific year or event. To answer this question accurately, additional reliable sources that document Disney’s merchandising history would be required.
