Antique Photo Victorian Couple, man woman Troy N.Y. Cabinet Card

I have found the photographs of the 1800s to be very interesting.  Often you can date these cards by furniture and other props found in the photograph.  Also the style of clothing, hairdos, whether ears are exposed.  (Early 1860's ears were covered on the women)   The earliest Cabinet cards were full portraits, later in the 1870's the hair was less severe, and photos showed only 3/4 of the person, not their feet.  In the 1880s and 1890s the womens clothes became my fitted, severe and suitlike.  In 1998 when postcards became popular there were less cabinet cards printed.  Of course I have found other cabinet cards that do not fit any area.
