The Garman Ryan Collection is a permanent collection of art works housed at The New Art Gallery Walsall and comprises 365 works of art, including prints, sketches, sculptures, drawings and paintings collected by Kathleen Garman and lifelong friend Sally Ryan.

Kathleen Esther Garman, Lady Epstein was the third of the seven Garman sisters, who were high-profile members of artistic circles in mid-20th century London, renowned for their beauty and scandalous behaviour. She was the model and longtime mistress of British/American sculptor Jacob Epstein, and eventually his second wife. They met in 1921 and immediately began a relationship that lasted until Epstein's death and produced three of Epstein's five children. Their daughter, Kitty Garman, was the first wife of Lucian Freud; their son was the artist Theodore Garman.
