Got at least $20,000 to burn?  PropstoreAuction.com has STAR WARS: THE EMPIRE STRIKES BACK (1980) 353. Yoda Puppet Head Skin, and as far as I'm concerned they can keep it.  The material used for the Yoda puppet was known to show some pretty visible signs of age, and now you can see it too.  The auction closes on August 26th, but you can sign in and bid now.  I guess.   Yoda did Luke a solid by just fading away in Return of the Jedi.

There are a lot of other worthwhile listings to check including storyboard art and a genuine Cloud City guard jacket which Hasbro might want to use when making us actual real new versions of the Bespin Security Guards rather than painting recycled arms and torsos.
