This piece went to Harvard, and then it was exchanged to Dr. Mark Feinglos at some point. It has resided since in his collection for many years. These come to market only in recycled collections of ultimate rarities, and are so few and far between that most of us are lucky to even see one go by. It is pretty small by some standards; but relatively speaking though it is a giant of a piece for what it is. It is of a size that the twinning is readily visible to the eye, in person.
