Barbie Loves Frankie Sinatra Collector Edition Gift Set (NIB, Mattel, 1999)

Serious question; who is yet to do a collab with Barbie? Because we believe that pool must be thinning out by now. 

I expect there to be a collab with Chris Hart in the near future, and perhaps also my grandma. 

Condition: Good, new in box. Box is a bit bent, and has been signed by someone we're not sure who is. The seller claimed it was the original dress designer, whom they met at a Barbie convention in the early 2000s - but we have no way of verifying this. 
The signature can easily come off, if you want to, however, as it's only on the plastic - but for now, we'll leave it as is.
