Hong Kong and Shanghai Banking Corporation, a pair of original hand drawn design essays for the face and reverse of a $50 note , produced by Bradbury Wilkinson, most likely by Derek Friday, the designs on paper in pencil, ink, and watercolour, measure 9.1cms x 16.7cms, curiously the face design is dated 1946, although the design strongly resembles the circulation note from circa 1930, this may have been a precursor to the later $100 note which has an almost identical reverse , in good condition with a small number of minor spots and stains and minor rounding of the corners
