I meant a daguerreotype that has been removed from its case. I don't know why.

This I am aware of, hence my need to protect it.

This was one of the pieces of information I was looking for. Was the metal
usually a piece of copper?

That's it exactly, and it needs a new case. Does Light Impressions make the
cases as well? I'll have to dig out my catalog.

I understand.

I have a collection of Ambrotypes, and this looks quite different. Yes the
image background looks like a mirror, and you get a negative image or a positive
image depending on the way you look at it. The base plate is clearly copper,
and on the front surface where the "matte" used to be is a bluish black tarnish.
Ambrotypes are done on glass plates, so I think this rules out that possibility.
I'd guess a combination of oxides from the copper base plate, and the silver
plating. There are a few reddish brown spots in the image as well (Daguerrian
measles?). I wouldn't say that this a spectacular specimen, but I thought for
$5 I could certainly give it a home. To the best of my knowledge this is just a
Daguerreotype that has been removed from its case.

Thanks for the information.
