Often mistaken as original artwork is the suite of four prints: "Bass Trio", "Hot Licks", "Quintet", and "In the Groove".  They were published in the mid-60s in Yonkers, NY., and circulate often via various online auction sites, listed as 'originals' or 'hand-painted serigraphs', most likely because many were printed on watercolor paper.  For any questions about this very popular suite--contact us :)
