Gentle Giant's convention exclusive will have a total run of 650, according to their booth on Preview Night.
From Gentle Giant's press release:
Digitally scanned from an authentic 3-3/4" vintage figure and reproduced to a substantial 12" tall, no detail has been overlooked in the making of this Star Wars Jumbo! Injection molded and made of durable plastics, this jumbo figure comes with his non-removable rocket, 5 points of articulation and his black blaster rifle, exactly like his vintage counterpart! This classic figure comes packaged on a 1983 Star Wars: The Return of the Jedi-inspired blister card with a resealable plastic outer clamshell to help protect and display this limited edition collectible on your wall, shelf or favorite showcase.
