When Empire Strikes back launched, we finally got to see what 'ole Boba Fett was all about but we were also introduced to his spaceship, Slave I.  Its toy debut included a few features that were unique at the time: free-moving wings that lock in position, remote operated pilot's seat, side panel for access to cockpit and ship's interior, clicking movable tail cannon, movable ramp to hold a frozen (in Carbonite) Han Solo!

 This factory sealed Slave I example is a first print / first release and is in excellent condition freshly graded in September of 2022 by CAS.  Encapsulated by CAS (80), #10197183
