Quoting from Sam's informative post above, "Some companies do not allow any unauthorized use at all, not even fan art or personal use. The most notorious in this case is Disney, and they have a bunch of very trigger happy lawyers who will jump up and down on anyone they catch using Disney stuff without permission."

So, I'm assuming all the free Star Wars related items - like the 2 versions of BB8 I have - would fall under the scrutiny of Micky's legal hellhounds? Hopefully they turn a blind eye to 'fan art' as well... Otherwise I'd have to remove my image of the Deathstar about to toast Kim Song Un... LOL
