Just had a close look at a 77 back and noticed a load of differences from the figures released. The obvious ones like the dark cloak squidhead and the red cape Bib Fortuna I've seen discussed before, but also noticed the:
Gold belt on Squidhead
Unpainted boots of Lando skiff
Orange/Brown cape Luke Jedi
White staffed Wicket
Are any of these floating around the collecting world?
Han Hoth with Bespin Blaster.
Hoth Rebel, Hammerhead and Walrusface with Han Solo/Rebel Blasters.
