I purchased this dining set about six years ago at an auction. It included one captain chair, three side chairs, and the table. Three of the chairs are stickered as 1960 and have all the proper markings. The fourth chair is stickered 1959 but it has an actual signature on it. If anyone has any knowledge of stickley furniture could you please look at the photos and let me know if the signature is of any significance. Thanks.
