The Declaration of Independence. The U.S. Constitution and Bill of Rights. The Monroe Doctrine. These bedrock documents laid the foundational "blueprints" of American democracy — and, some of the earliest printings and engravings of these iconic pieces will be on view at the Oregon Historical Society (1200 SW Park Ave., Portland) from July 29 through Feb. 1, 2017, in the original exhibition “Democracy's Blueprints: The Documents that Built America.”
