Here is a picture of insulators from a recent purchase of a collection that will be at the DuPage Collector's Expo show in Wheaton, Illinois. Most of these will be in the dealers-only auction held in the evening before the show on Friday, April 5. This is part of the third big collection committed to the show. Shown are some broken threadless, a white porcelain mine insulator, a big spool, a pin base, and more.
