The Ronald Reagan Presidential Library and Museum in Simi Valley, Calif., has opened “D23 Presents Treasures of the Walt Disney Archives,” the largest Disney archives exhibit in the world, presented by D23: The Official Disney Fan Club. The 12,000-square-foot exhibition features showcases more than 500 Disney artifacts, many publicly displayed for the first time, from more than 100 years of Disney history.

The collection includes early original drawings of Walt Disney’s first cartoon, “Oswald the Lucky Rabbit”; the first ticket ever issued for Disneyland; Walt Disney’s formal office; Disney theme park attraction pieces and ride vehicles; and props, set pieces and costumes from Disney films, including “Mary Poppins,” “101 Dalmatians,” “Pirates of the Caribbean,” “Tim Burton’s Alice in Wonderland,” “TRON,” “TRON: Legacy,” and “Marvel’s The Avengers.”

In addition, an entire section is devoted to items that celebrate the connection between Walt Disney and Ronald Reagan. Photos, letters (including a hand-written draft of a letter from Reagan to the U.S. Postmaster General urging the creation of a special Walt Disney stamp) and an assortment of archival items underscore the close personal and professional relationship between the two men.

The exhibit is open every day of the year, except Thanksgiving Day, Christmas Day and New Year’s Day, during regular Reagan Library operating hours. Entry to the exhibit is included in the price of regular admission. To purchase advance tickets, visit www.reaganlibrary.com/tickets. Tickets also are available from the Reagan Library box office. D23 Members receive a discount on tickets to the museum and, along with members of the Reagan Foundation, can visit the exhibit 30 minutes prior to its public opening each day.
