David Mathias wrote on the Greene Style Furniture mailing list recently that he had seen a number of items of "Roycroft pottery" for sale on Ebay. As many collectors know, aside from a small amount of china used on the campus and produced by Buffalo China, the Roycroft mark never appeared on any commercially-produced pottery until the current resurgence of the movement, and to this day nobody knows what the original experiments looked like as none survived.
David did a little investigation and noticed the vase for sale was a beautiful trapezoidal dragonfly design by potter Janice McDuffie, part of the current Roycroft Renaissance, who has been selling her work under the apt name Roycroft Pottery since the late 1970s. It certainly is Roycroft pottery - but it is not a rare antique, and the seller was allowing the price to climb far above the actual cost of buying such an item new - and they certainly are available! So rather than the money going to the artist who made them, an Ebay seller was withholding information about the item and allowing the price to be inflated for their own personal gain. Certainly they have that right, this behavior is frowned upon in the antique business and the buyers should be made aware of whole truth about the items they are bidding on, especially when it comes to handicraft items. David did contact all of them - and none responded. It seems they enjoy being taken to the cleaners, and if so, then let them get what they want.
Example: Ebay user (deleted) (whom I have communicated with, and whom understands the problem - (s)he has contacted Ebay to change the description and make clear that this item is neither antique nor hard to acquire new) has this item, which costs $100 new, up on Ebay now; the reserve has not yet been met even at a current bid of $152! Janice would be glad to sell anyone who asked for $100, and then you'd be dealing with the artist herself. So - please bid responsibly, and don't support unscrupulous dealers.
