Sixth-plate daguerreotype.. looks like he's wearing a type of bridge coat with vest? Very confident pose... he might have been somebody notable..
Dag is in very good antique condition with a tarnish ring including that heavy vertical line of tarnish on the right side. The original seals have dried up and fallen down into the case, but besides the tarnish the plate appears to have no damage.
Location is not definitively known, but this dag was purchased along with another daguerreotype that was taken by Portland, Maine photographer Samuel L. Carleton. This dag does not have a photographer ID, but it's possible, based on the Carleton dag, that this was taken in and around Portland, as well.
Full, complete leather case with no repairs, double clasps, separated covers.
