The Washington territorial seal has advanced to the quarterfinals of our Archives Treasures tourney after knocking off the 38-star 1886 U.S. flag 58 percent to 42 percent. We’re down to our last of our eight first-round games. It’s the 1859-60 Crosby Store ledger against the 1857 map of Washington Territory. We’ll start the online poll for that matchup this afternoon, so be watching.
