From the BBC:
Three wax heads of The Beatles, made for Madame Tussauds and used on the cover of the Sgt Pepper's Lonely Hearts Club Band album, are to be auctioned. Auctioneers Cooper Owen expect the busts of John Lennon, Ringo Starr and George Harrison to fetch up to £80,000 when they are sold later this month. Also included in the sale is a waxwork head of Sir Paul McCartney that was not used in the album cover photo shoot. A bust of actress Diana Dors that was on the album cover is also being sold. "The auction provides a once-in-a-lifetime opportunity to own a piece of definitive cultural history," a Cooper Owen spokesman said.
It would be fun to burn them and imagine you were watching a horror film about a lunatic fan who imprisons the Beatles, chops off their heads, and then sets the house on fire. Or could you put display them in some kind of memorabilia room.
