LONDON — Art lovers who can’t afford a painting by Francis Bacon can bid on the late artist’s paintbrushes at an auction of unusual items.

The eight brushes, given by Bacon to fellow artist Clive Barker in 1978, are in a paint-splattered butter bean tin inside a clear box.

They have an estimated price of $31,000 to $46,000.

Bacon’s paintings have sold for as much as $86 million at auction.

Also among the 150 lots in Christie’s Out of the Ordinary sale: a rocking horse as tall as a house; a flying machine from Steven Spielberg’s “Young Sherlock Holmes”; a stuffed ostrich; and a triceratops skull valued at between $234,000 and $290,000.

The sale will be Sept. 5 in London.
