China 1914-19 $10 black and green, Peking printing, 'Entrance, Hall of Classics, Peking', SG307.
A fine mint example, very lightly hinged and particularly fine for this issue.
These classic definitive stamps were initially printed in London. The printing was then transferred to Peking from 1914 to 1919 where the designs were re-engraved. The $10 stamp is the highest value and rarest of the issue.
