No two misprints are alike – and this one is something special. This Chewbacca Wookiee head (15307pb03, Dark Brown) carries its distinctive Medium Nougat face fur print with white snow spots on the wrong side of the mould – and visibly offset at that. A genuine LEGO® factory misprint, the kind that rarely makes it past quality control.

For missprint collectors, Star Wars fans, and anyone who knows: production errors aren't flaws – they're rarities.
