Hi,
On another note, I collect Daguerrotypes. They are the first photography from the 1840's and 1850's. They are the ones on polished silverplates. There were no negatives yet so each one is unique. One exposure one Daguerrotypewith no copies possible (without re-photographing the Daguerrotype)
There is an ebay seller famous for his "Embellishments" of them. He seems to find one that looks vaguely like someone famous and then sells it up as being a previously unknown photo of them. He offers them at hundreds or thousands of dollars. When people bring up that these are not of famous people, he gets VERY defensive and accuses people of trying to sabotage his legitimate sales and questions their ability to know. Of course his listings are worded vague enough so that he said that he "believes" this to be an unknown image of this person. No guarantees, etc...
There is big money in these things. A common Daguerrotype sells for about $75 in good condition (and a common type pose). Recently a previously unknown image of Poe surfaced (At the Antiques Roadshow of all places) and it is worth over $50,000 (She paid $96 for it at an antique shop), plus it is such avaluable piece of history. I think that Poe was only photographed three or 4 times and one of them was of his corpse.
