I thought it MAY be a Rey or Finn lightsaber variant Pop! which would've been awesome. Then I thought, "Hey, there's no old man Han Pop! figures out there, so maybe it'll be him!" I actually never considered Chewie done this way (like they did Wolfman for classic monsters) and was surprised!
He does have a little scuff by his mouth, which is unfortunate, but my wife is a Chewie lover, so she's probably going to steal him anyway.
The shirt is awesome, and the mug is fun! The only thing I'd change is the pin. I'd prefer the BB8 picture on the pin over a Resistance fighter, but I'm guessing they wanted to mix it up a bit. Overall solid box though!
