Original roll of Star Wars wallpaper from 1977 valuation

[WeBrake4Wookies]

Hi there I have been given a roll of wallpaper from my dad which he got in 1977. It is in immaculate condition and is apprx 8-10 metres long. Can anybody give me a rough value of this product as can't find anywhere on the internet?

I've picked up a few sealed rolls over the past year or two. I normally pay about £30-£35 a roll.

Hope that helps.
