Autographs of Howard Marks

Dennis Howard Marks (13 August 1945 – 10 April 2016) was a Welsh drug smuggler and author who achieved notoriety as an international cannabis smuggler through high-profile court cases.
At his peak he claimed to have been smuggling consignments of the drug as large as 30 tons, and was connected with groups as diverse as the CIA, the IRA, MI6, and the Mafia. He was eventually charged by the US Drug Enforcement Administration, convicted and given a 25-year prison sentence; he was released in April 1995 after serving seven years. Though he had up to 43 aliases, he became known as "Mr Nice" after he bought a passport from convicted murderer Donald Nice. After his release from prison, he published a best-selling autobiography, Mr. Nice (1996), and campaigned publicly for changes in drugs legislation.
Marks was born in Kenfig Hill, near Bridgend, Wales, the son of Dennis Marks, a captain in the Merchant Navy, and Edna, a teacher. Brought up as a Baptist, he later turned to Buddhism, though he did not become a devout follower. He attended Garw Grammar School in Pontycymer. He was a fluent Welsh speaker.
