A priceless 4-page 1843 British Foreign Office Circular

A priceless 4-page 1843 British Foreign Office Circular (see below) alerting British Consuls about the legal penalties placed upon British subjects still involved in the Slave Trade. This absolutely rare document is personally handwritten and signed by Lord Aberdeen, who later became Prime Minister of Great Britain (1852-1855). Lord Aberdeen wrote this while he was the British Consul at Trieste, Italy.
