“Antiques Roadshow,” PBS’s most watched prime-time series, returns for its 18th season tomorrow at 8 p.m. on WGBH Channel 2 with highlights from last season’s visit to Boise, Idaho, where one of the highest valued finds of the season was discovered.
It was a painting of a an Italian landscape by the Hudson River artist Sanford Robinson Gifford (1823-80) that had been inherited and relegated to the owner’s basement. It was appraised at $300,000.
Among the other treasures found in the Gem State were a first edition of the Book of Mormon, a 1955 Picasso Madoura ceramic plate, and a 1974 end table signed by George Nakashima (1905-90), the master woodworker and furniture designer.
