I figured since all the other sections have a thread like this why not here.
I'll start it off with the latest edition to my collection:
Star Wars - Darth Vader: Ralph McQuarrie Concept Mini Bust.
As a fan of McQuarrie's concept art I was pretty excited for this bust and it turned out great. It has 3 different interchangeable heads (all pictured below) so you can pick your favorite look. The heads are held on by a very strong magnet. Unfortunately, unlike the Concept Boba Fett bust, the bottom of the helmets are not flat so displaying the 2 extras loose around your bust could prove challenging. This is something I'd like to do so I'm going to look into finding something for them to sit in so they stay upright.
Anyway here are the pics.
