Sarah Lucas is also known for her self-portraits, such as "Human Toilet Revisited", 1998, a colour photograph in which she sits on a toilet smoking a cigarette. In her solo exhibition "The Fag Show" at Sadie Coles in 2000, she used cigarettes as a material, as in "Self-portrait with Cigarettes" (2000). And in 2001, Sarah Lucas used Neon tubes for her artwork ‘New Religion’ in which a transparent coffin has been lit up violet. It was later acquired by George Michael in 2004.
