13 pieces GGN auction catalogs (new pieces)

Especially useful, given the lack of an online archive. It's possible that many collectors don't even know that the collection ornaments they own may come from one of these auctions. GGN in those years was a top auction house competing with WCN. New unused pieces: numbers 2, 5, 6, 7, 13, 21, 23, 25, 26, 27, 30, 33, 34 (from 1991-2005).
