I purchased this card on eBay this morning. I have seen plenty of the chemical treated T206 cards, even owned a couple, and feel like I can identify one when I see one. The scans look good to me, in other words, I don't see anything that cries out "chemically treated". And, since the seller offered return privileges and has very good feedback, I decided to take a chance. Once it arrives, I will decide whether or not to have it graded.

The only reason I posted about this card is that I am curious about how this particular color was achieved. Usually, color variations are the result of one or two missing layers or colors in the printing process. You can usually tell, for instance, that the variation is due to missing yellow or red ink, or whatever color it might be. So, assuming there is no chemical alteration, how might this color have been accidentally created?
