The tissue is being auctioned by US chat show Tonight with Jay Leno
One of Scarlett Johansson's used tissues is being offered for sale on auction website eBay.
The actress was appearing on US talk show Tonight to promote her new movie, The Spirit, when she said she'd caught a cold from co-star Samuel L Jackson.
Host Jay Leno handed her a tissue and Johansson blew twice, depositing some lipstick and mucus. She said she would sell it for hunger charity USA Harvest.
The highest bid is currently $2,205 (£1,465). The auction ends on Monday.
Listed as "own tissue from Scarlett Johansson and Sam Jackson", it is only available on eBay's US site.
During her TV appearance, Johansson told Leno she thought her illness had more "value" as it had been passed from one celebrity to another.
It is not the first time the Lost In Translation star has used eBay to raise money for charity.
In March a fan paid £20,000, which went to Oxfam, for a 20-minute date with the Hollywood actress.
