Ambrotypes!  Rooms No. 1 Main Street The subscribers have the pleasure of announcing to the citizens of Bangor and vicinity that they have recently opened a new and spacious suite of rooms in the city for making Ambrotypes.

The genuine Ambrotype, (among other things that distinguish it from all other pictures), is taken upon fine plate glass, upon which is placed another glass, the two being united by an indestructible gum, thus effectually securing it from dust, dampness or liability to damage from any source.  The pictures are not reversed, are free from that unpleasant reflection peculiar to the daguerreotype, and are the only photographic pictures that do not change.

Those having pictures they wish to preserve, can have them copied by this process.

The public are respectfully invited to examine the pictures at our Rooms, Entrance next door north of No. 1 Main-st.

N. B.  The genuine Ambrotype can be obtained only at our Rooms.  Hartford & Stoddard.  Bangor, Aug. 30, 1856.

Advertisement was recorded from February 16 to May 14, 1857.
