I believe that this is an Antique Daguerreotype photograph of an early type of train locomotive. If the photo is tilted to the light the image has a silvery reflection. the case size is 3-11/16 X 3-5/16 inches Please see the photos for condition. Please ask any questions you might have before offerding. If anyone has any info on this item I would like to hear from you. On Jun-11-13 at 14:10:50 PDT, seller added the following information:
I have been told by a fellow er that he is 99% sure the the photograph is an Ambrotype and not a Daguerreotype. Please use this info to determine how much you are willing to offer.
