Information:503-282-0877 or http://www.palmerwirfs.comIt could have been right off of television: Robert and Marcia Stewart waited for two hours in line. They paid $10 and placed their two items — a 1930s Mickey Mouse sweatshirt that was Marcia’s mother’s and a 1925 art deco Pabst Blue Ribbon lamp that was her grandparents’ — into the knowledgeable hands of appraiser Kathleen Victor. Victor gives details about the pieces, such as that Mickey’s long nose shows indicates this is the first version of the mouse, and that the lamp base and top are ruby amethyst. It’s all very interesting but — and viewers of Antiques Roadshow know this look — what the Stewarts, and everyone watching, clearly want to know is: What are they worth?The Mickey sweatshirt could bring $450 to $500 in a Disney auction. The lamp, which Victor says appeals to collectors of art deco, nudes and beer memorabilia, could get about $600. “You can sell naked ladies all day long,” said Victor of the lamp, which featured a zaftig woman in a state of undress with flowing locks, under the painted-on Pabst logo. “She’s got everything somebody wants as far as selling beer.”Startled smiles ran across the faces of the Vancouver couple: A $2.50 investment on that lamp more than 30 years ago may net them a profit of about $597.50.
