There was a variation for the Vintage Collection Boba Fett VC09 figure which was released in June/July 2010. The first version (pictured left) had a dark green cheek color on the helmet and the blaster rifle had a silver tip. The corrected version had black cheeks and a black rifle tip. The boots, shoulders and knees also look slightly different with subtle color changes across the armor.
TVC Boba Fett (Empire Strikes Back) variation, pictured on the left is the first version, on the right the corrected 2nd release.
