Dirty Harry / Magnum Force

The length of the barrel of the Magnum 45 was the most significant feature of its popularity and is used to good effect here in this cleverly designed American combo. "Double Trouble!" is the tag-line as Clint Eastwood takes on the role of Detective Inspector 'Dirty' Harry Callahan in San Francisco - the tag-line is even more appropriate for this 1975 film poster featuring 'Dirty Harry' and 'Magnum Force' together for the first time. The film poster has been backed onto linen.
