How old would Sylvia Sleigh be today?

Sylvia Sleigh was a Welsh-born naturalised American realist painter who lived and worked in New York City. She is known for her role in the feminist art movement and especially for reversing traditional gender roles in her paintings of nude men, often using conventional female poses from historical paintings by male artists like Diego Vélazquez, Titian, and Jean-Auguste-Dominique Ingres. Her most well-known subjects were art critics, feminist artists, and her husband, Lawrence Alloway.
