A collection of documents and other pieces relating to penicillin discoverer Alexander Fleming is to auction at Bonhams.

Fleming Penicillin Bonhams

Alexander Fleming discovered penicillin by accident

The lot will feature photographs, letters and a sample of penicillin mould bearing Fleming's signature on the reverse. It’s offered as part of the March 1 Fine Books and Manuscripts sale in London.

Fleming made an extraordinary contribution to medicine and his memorabilia is growing increasingly valuable.

This lot is valued at £6,000-8,000 ($7,490-9,987).

A piece of the original penicillin mould culture sold for double its estimate last year, achieving $40,000 against a valuation of $20,000.
