Bosses at the Sheffield Auction Gallery in England were planning to put a collection of items from the band's formative years up for sale on 30 September (16), but the planned sale has been cancelled after officials revealed the Osbourne family bought every item available.
"The items have been sold by Private Treaty, for an undisclosed sum, to the Osbourne family, ensuring that this important piece of 'hard rock' musical history remains intact," gallery auctioneer Stephen Flintoft says in a statement.
Among the paraphernalia that was slated to go under the hammer were handwritten lyrics, posters, photographs and postcards written by Ozzy himself.
According to Rolling Stone, the collection was taken from a building in London's Docklands just before the area was demolished and rebuilt in the 1980s.
The items are mostly from 1968 to 1972, when Ozzy, along with Tony Iommi, Geezer Butler and Bill Ward, first joined forces as the Polka Tulk Blues Band. The rockers eventually changed their named to Black Sabbath in 1969, after being inspired by the 1963 horror film of the same name.
