Yes, I saw these too. Obtained in Sweden I think. It is a nice set but for the money asked I'd want Starr rather than Nicol - even if a Nicol set would be much rarer.
Very nice set. As Nike says, just do it! You know you want them, Michelle. All you have to do is exchange pieces of paper for even nicer pieces of paper.
By the way, I meant to add a "LOL" to that! Just kidding. I don't even know how much they cost, although I imagine those sigs are rather expensive ones.
Nice set. Just remember, it's really only worth what an incomplete set is worth. Unfortunately, on the resale market, having 3 of 4 is only worth about 30% of having all 4. Go buy one of Ringos overpriced pieces of art and maybe he will sign it for you.
