Description: Tsingtau, China. 1927, 20 cents, P-143Aa, S/M#C126-181b, Blue face with steamship on left and locomotive on right, back orange-yellow with black English signatures, the blue color variety is unlisted in a 20 cent denomination, only as a 10 cent note. Evidently it was given a new catalog number by PMG but they made a mistake with the Smith Matravers catalog number. PMG graded Very Good 10 with no edge faults, just toning, still the note has bright colors and will enhance any advanced collection. This is the only graded note in the PMG census and is extremely rare if not unique. W&S.
