For those into variations there is one already on The Black Series 40th Anniversary Legacy Pack. Hasbro has changed the paint color of Vader's Helmet Lens.
• 1st Version (DS 70121) Red Color Lens
• 2nd Version (DS 70681) Smoke Color Lens
I have only seen the earlier version (red color lens) at Target and the smoke colored lens version at Walmart, GameStop, and Best Buy.
