Interesting that George is wearing an ESB crew jacket considering the efforts they took to hide the ROTJ location shoot under the Blue Harvest name.
And I wish they made those jackets now.
You’re 2 years too late! Columbia did make a limited edition reproduction of that jacket in 2018!

You can find them for sale on eBay still. At a markup, of course.
