Sam Francis's *Blue Bones (sf-64) (Lembarк L.77)* is a vibrant, lyrical composition characteristic of the artist's celebrated Abstract Expressionist style, featuring luminous washes and dynamic bursts of color that seem to float and breathe across the surface. Francis's signature interplay of saturated hues and open white space creates a sense of expansive movement, evoking both organic forms and cosmic energy. The work reflects his deep engagement with light, color, and the gestural freedom that defined his prolific career.
