One of his most valued parallel sets, here are the few that I own:
1997-98 Metal Universe Precious Metal Gems Red /100
Just as in the case of Jordan, the Green version /10 has been unattainable. There were a few copies overseas that it seems one collector bought all at once. I will most likely never own the green, but it's something I've pretty much accepted.
1997-98 Metal Universe Championship Preview /50
The most gorgeous of the PMG's in my opinion. I have been searching high and low for another copy of this without success.
