Prized 'Star Wars' memorabilia that belonged to Peter Mayhew, the actor who famously played Chewbacca, is about to go up for auction ... and unrightfully so, according to the late actor's wife.
Angie Mayhew tells TMZ ... she's very upset an auction house in the UK is selling a ton of Pete's possessions from his 'Star Wars' days, including scripts, call sheets, signed photos and more.
The collection was given to Ryedale Auctioneers by a couple who moved into Peter's old home in northern England and found the items in the attic.
The couple didn't know the memorabilia once belonged to Peter, so they unwittingly gave it all up.
Angie tells us when they were moving out of the home, Peter attempted to snag his mementos from the attic, but couldn't get inside due to serious knee issues ... and he didn't want Angie to risk injury going up there herself.
She says Peter scooped up as many items within arm's reach as he could, but had to leave the rest.
Angie says leaving the memorabilia was one of her and Peter's "biggest disappointments" in life.
On Tuesday, Peter's wife saw the items were up for auction, and immediately got honchos at the Peter Mayhew Foundation to contact the auction house. Angie says she plans to speak with the auction house Thursday.
You'll recall, the iconic 'Star Wars' actor died back in 2019. Angie is hoping to reclaim the items and put them on display in the family's "Chewy" museum in Texas.
As of now, the items are set to go on the auction block on Feb. 17 and 18. We reached out to Ryedale Auctions ... so far, no word back.
