When I lived in Louisiana the Road Show came to New Orleans. I took a couple of items to it. One is an adjustable shelf that can tilt from straight vertical to fully horizontal like a table. Everyone around me said they had never seen one like it. I thought it ought to be worth many hundreds, maybe even a few thousand. The appraiser said it came from a period when mechanical furniture was popular and was worth something on the order of $400. The other item was an "all in one" hand tool with changeable bits, like tack puller, awl, sack needle, a few screwdriver bits, etc., dating back to the early 1900's. The bits were stored in the hollow handle and the cap screwed on. Handle and cap are wood. The appraiser said it was Brazilian Rosewood and was in the best shape and most complete he had ever seen. Value? About $40. What a disappointment that trip was!
