A long time ago, I was given some really old pics.  All of them prints
and negs from the early '20s and some even older.  But one in
particular was different from all the rest.  It caught my eye because
it was so unique.  It's just a bit bigger than a wallet size, but it
isn't a print.  The image is on glass!  Framing the glass is what
looks like fancy gold tin foil.  The image is of a lady in a big hat
wearing a beautiful dress right out of the 1900's.  It's in good
condition and the image of the lady is very sharp.  I put it away to
keep it safe years ago.  The problem is I can't remember where I put
it!
Would you know what kind of process they used to put an image on
glass?  Just curious.
Thanks Ken,
