BTW, another tidbit I use to determine authenticity, though very unscientific, is the way something is being sold. On this M110, sold by a board member to me on ebay, if I recall correctly, it was NOT touted as a Chief Meyers signature. It was just said to have writing on it. I didn't know it was a Meyers auto for several years, therefore there was no financial motive on the front end sale. To me it gives a bit more comfort that it might be real, and of course the JSA authentication after the fact helps too. Here is a W515-1 with an overprint/stamp (one for ya' Rob) and I got it not too long ago, and again the stamp on back was barely mentioned. The card went for under $70.....so, no financial motive on it, means it's more likely to be good, at least to me. Just some random thoughts....
