Raw, in broad daylight on eBay right around the time I joined this site or soon after. I imagine it is worth a bit more now. ;) The best I can remember is a $68 signed candid of Judy Garland at the second premier of The Man with the Golden Arm from the Grace Cunningham Collection of signed TV candids (the image was dated by Garland Historian Scott Schecter - now I could do that myself. ). Steve Grad said it was a "steal."
PS - Very little I like more than getting a great deal on a great item. Not so frequent anymore to be sure, but I still see good items from time to time.
