This is the original, rarely to market, strikingly rich 1989 Robert Cottingham "Blues" aquatint - from the very limited edition of only 45 (not to be confused with the later, and less valuable 2009 silkscreen reprise done two decades later, from a larger edition of 100). This work was part of the collection of a major law firm and is in its original metal vintage 1980s frame. Ready to hang.
