The trademark bullwhip used by Harrison Ford during his 1981 debut as Indiana Jones is set to be auctioned off in London later this month.

Jones famously cracked the brown leather whip throughout his time playing the adventurer, and the specially crafted item, which appeared in the hero's first outing in Raiders of the Lost Ark, is now up for sale.

The whip will be accompanied by a letter from the film's special effects boss Kit West, confirming the piece's authenticity, when it goes up as a lot at Bonhams auction house in the U.K. capital on December 15th.

The estimate price is between $48,000 and $56,000.
