I can't afford a vast collection of Chess sets, but I am collecting images of many interesting and unusual pieces. Some are commercially available (those images will have links), but many others have been fleetily glimpsed while browsing ebay auctions, etc. I am gradually putting together a series of pages and pdf documents, so you too can enjoy the variety of unusual designs of Chess sets. I have gathered plenty of links to On Line Sources for Unusual Chess sets.
