Ileana Sonnabend; and Leo Castelli, from Purple series

Frank Stella's *Ileana Sonnabend* and *Leo Castelli* are bold lithographic prints from his celebrated Purple Series, each bearing pencil signatures and edition numbers (60/100 and 68/100 respectively), alongside the prestigious Gemini G.E.L. blindstamp. The works exemplify Stella's rigorous geometric abstraction, employing his signature concentric and interlocking forms rendered in deep, commanding purples. Published by the renowned Gemini G.E.L. workshop in Los Angeles, these prints reflect the artist's masterful collaboration with one of the most celebrated print studios of the twentieth century.
