I happen to be the high bidder on both of these striped opaques, the one from marbleus1 and one from Alan....they are both great examples of this type of CAC but was a little concerned of a smeared looking area on the the marbleus1 auction. I do not question David's integrity, I believe he is a man of his word. I was just hoping this marble had not been spot polished by hand by a previous owner.
