(Portland, OR) -- The first known U.S. flag to be raised over Portland is on display at the Oregon Historical Society. Portland resident Ann Elizabeth Bills hand-stitched the flag in 1861. It's been displayed several times folded inside of a case, to protect the fragile materials. The flag has undergone restoration work that now allows it to be displayed in its full size of nine-by-six feet. It's on display with a 1774 document on the First Continental Congress and two maps from 1817.
