Antiques Roadshow, the Public Broadcasting System's highest rated show, is now in its 18th season. Each week 8 million viewers tune in for the mixture of treasure hunt and history lesson tales of valuables discovered in thrift stores, yard sales and attics. The show has garnered 11 Emmy Award nominations and spawned a host of other shows with similar historical treasure hunt themes.
Among the most valuable items on the show was a collection of jade that a woman's parents had bought in the 1940s in China valued at $1.7 million.
More recently one Boise woman brought in a poster that her mother found at a yard sale and paid $200 for. The poster of a young bathing beauty was done by Earl Moran, an illustrator who was born in 1893 and died in 1984. The piece, mixed media on board, was appraised at between $20,000 and $30,000.
