Thanks Edna, I knew there are white Blackies. That is, Blackies that are missing the color patches. And I imagine that those marbles were produced using the same white base as the rest of the Blackies. I also believe that Vitro would have used a less expensive white for the base on these marbles, since it most often completely covered anyways. On the other hand, the whities are largely white, and I propose that the base on those marbles is a higher quality white than used on Blackies, since it made up the majority of the marbles surface. I also propose that Vitro made black Whities. Do you know anything about that? I know you have a considerable number of both types, would you mind comparing the white bases and letting me know what you think? Thanks Again, -Ric
