Extra-large playset. Impressive Toys R Us exclusive release from over 20 years ago. Outstanding color and display value. This is the only 2001 Headquarters example ever graded by AFA and it looks absolutely gorgeous encased in the custom acrylic. Factory tape sealed on one end and tape broken on the other. Color break is present along the broken tape end. Showstopper of a piece – the winner will not be disappointed with this one! Approximately 31.5 x 7 x 17 inches.  Encapsulated by AFA (80q), #11881059
