Appraised in Chicago (conclusion): an 1820s classical-revival secretary; a Grant Wood painting; an 1822 U.S. atlas; a trombone owned by a member of the John Philip Sousa band; an 1850s Tiffany gold necklace; and a "presentation piece" (photos) honoring the 1908 Chicago Cubs---the last Cubs team to win a World Series. Also: host Lara Spencer asks "Roadshow" attendees at the Chicago Navy Pier to define the French phrase "sang de boeuf."
