The Imperial Commander. Not the most interesting figure at first glance perhaps, although it should be noted that Julian Glover became the only Star Wars film actor who showed his face on screen that had not one, but two different figures made of his character, neither of which is called the character's name (excluding the Canadian vac-packed 'General Veers' mega-pricey MOC). That piece of trivia aside however, there are a surprising number of variants to be found on what many regard as a bit of a dull figure. There's short and long boots, fat and thin face, pink and pale face, long and short neck, rough and smooth tunic, bent and straight thumb (and it's not just the PBP that can be found with a bent thumb either) and various shades of brown hair.
Here's my eight, including a pair of oddities bought on eBay years ago which the owners decided to 'improve' with blue paint! I wouldn't bother including them here, but defaced though they are, they are actually different variants.
Lastly, there's also the world's most battered 30B Palitoy MOC! It's certainly seen better days, but it is still fully sealed
