These are kind of like the one Don Lueders posted awhile back of Wilbur Clark. They are quite interesting.
BTW, yes, I do sell these holders. They measure 2 1/2" by 3 1/2" with a 2" mylar opening. They fit perfectly into baseball card sleeves and pages, and also into the vault boxes that are for slabbed (dirty word, I know) coins. They are $12.00 per 100 shipped UPS or $14.00 per 100 shipped through the post office. eMail if you want some.
