Star Wars Wall Paper Worth?

[Rigby]

Just curious if anyone out there knows how to find out the worth of something Star Wars related. Back in 97 a friend gave me in a frame one panel of the 1978 Star Wars wall paper that everyone had on their wall when I was a kid. She got it from a guy who had a roll of the paper and he was selling individual panels for I think maybe $80 bucks back then. It’s still in perfect condition. Is there any way to find out if it’s worth anything? Thanks!
