An inexpensive guitar given to George Harrison on his 12th birthday is part of a large lot of Beatles memorabilia put on the block by London auction house Cooper Owen on Nov. 20. The wooden, steel-string guitar was the first such instrument Harrison owned and the one on which he learned to play. The guitar is expected to sell for around $450,000. Other items in the catalog include promotional items, photographs, clothing and original art. The auction will take place at the Hard Rock Cafe on London’s Old Park Lane and entrance is by catalog only.
