you answered your own question. That's why it's called the Obama figure. No announcement from HT. HT occassionally releases nudes, and figures for that matter, with some resemblance to actors. For example, the TT AA slim has some resemblance to Terrence Howard. The other advance nude looks like the guy from Prison Break. It's just an added bonus that they look like someone for customizers.
So does the actors/politicians they resemble have to approve them before HT can use the 'somewhat' likeness? Does Obama, Howard, etc. get paid by HT for having the headsculpt resemble them?
