The veteran star passed away following a suspected stroke at her home in Spain on 1 August (15), and just 10 days after the tragedy, it has emerged a handkerchief autographed by Black during the 1960s is to go on sale.

The item, signed "Luv Cilla", is expected to fetch just $48 (£30) and will be just one of the lots at the annual Beatles Auction in the legendary band's hometown of Liverpool, England later this month (Aug15).

Other memorabilia forming part of the 2015 sale include a school detention note documenting John Lennon's "noisy" behaviour in class in the 1950s, due to fetch up to $4,000 (£2,500), the front door to George Harrison's childhood home, worth up to $1,600 (£1,000), and strands of his hair, which have a starting price of $320 (£200).
