There is one Hallmark ornament seller on Ebay that declares he has "thousands" of ornaments for sale.  He has a few, not thousands, and  most of the ornaments he has left were taken from his exwife's collection.  He states he has been a collector since the beginning of Hallmark, which is not true.  He inherited the original ornaments he has from his deceased wife's collection.  He told his exwife he had sold the ornaments she requested in their divorce but has since been selling them or exact items to those she requested on Ebay.  This may not be much help to most but at least will let you know who/what you are dealing with.  He has great feedback but has been known to have things in his possession that are not legally his or items that were aquired in ways that were not always legal.  Just beware of this seller.
