We cornered the market on Opal Open, early, late, small, large, even one milkglass. We would like to contribute pictures (we haven't taken yet) to a research project. Also would like to get rid of most of them and other old Northwood pieces. We also have the baskets that look like they are from the same form and one carnival glass one that we want to keep. Hate to sell them one by one before someone catalogs them for a museum or a book.
