This is really interesting, it is a business letter written from Calcutta, India, in 1847 concerning a very large shipment of coffee (200 packages of Choka coffee to be exact) being sent to Hamburg Germany, organized by the firm of Walker, Ireland & Company.   Condition is good, very readable, paper is very lightweight and has the red/orange "India Letter" stamps from the British-Indian postal service. Buyer to pay shipping, good luck!
