Whitmore & Porter (also spelled Whittemore) were recorded in three advertisements and two announcements in three different newspapers.  The first announcement appeared on April 22, 1842 I the National Eagle (Claremont, New Hampshire).   Daguerreotype Miniatures.  We would call attention to the advertisement of Messrs. Whitmore & Porter in another column.—Those of our friends who may wish to have an exact impression of their faces transferred upon steel, can now have an opportunity.  We know nothing about the operation of the Daguerreotype, but the specimens show us are exceedingly beautiful, and such as could only  have been produced by one having a through practical knowledge of the instrument.  There is no quackery here, and if our citizens will favor the above gentlemen with a call, we will guarantee them a gentlemanly reception.

The first advertisement ran on April 22 & 29, 1842 in the National Eagle.  Pencil Of Nature.  Messrs. Whitmore & Porter, respectfully inform the citizens of Claremont, that they have taken rooms and set up their apparatus for taking Daguerreotype Miniatures, at the Tremont House and will remain there a few days, where they will be happy to exhibit to the Ladies and Gentlemen of Claremont, specimens of their work, and render such other attention as may be necessary for their information.  Those who have never seen a specimen of nature’s pencillings can hardly form an adequate idea of the extreme perfection, beauty, and wonderful minuteness of a Daguerreotype Picture.  Suffice it to say that productions of this process are the works of nature, and not of art-the light of heaven alone is the pencil used.                     

The second advertisement ran from June 28 to July 12, 1843 in The Middlebury People’s Press  (Middlebury, Vermont).  Pencil of nature.  Messrs. Whitmore & Porter, respectfully inform the citizens of Middlebury and vicinity, that they have taken rooms and set up their apparatus for taking Daguerreotype Miniatures, at J. C. Huntington’s Hotel, and will remain there a few days, where they will be happy to exhibit to the Ladies and Gentlemen of Middlebury, specimens of their work, and render such other attention as may be necessary for their information.

The second announcement appeared on July 5, 1843 in The Middlebury People’s Press.

Daguerreotype Miniatures.—As our citizens have never before had an opportunity to witness specimens of this kind, and the manner in which faces and objects are painted by nature, as perfect as life, they will do well to call at the rooms of Messrs. Whitmore and Porter at Huntington’s where they will remain a few days.

When it was first announced to the world by the light of Heaven alone the most perfect and minute similitudes of nature’s works could be painted, it was deemed almost incredible.  But its reality is now as certain as human existence, and as like every other art in its infancy it is susceptible of vast improvements, it is likely to produce as great a revolution in pictorial productions, as steam in maritime operations.  Let the people gratify a laudable curiosity in relation to this wonderful art, by calling upon the gentlemen now at Huntington’s, who promise to render every attention necessary for the information of visitors. 

The third advertisement ran from December 15, 1843 to January 12, 1844 in the Burlington Free Press (Burlington, Vermont),  Daguerreotype Miniatures.  Mess. Whittemore & Porter, Respectfully inform the citizens of Burlington that they have taken rooms and set up their apparatus for taking Daguerreotype Miniatures at the American Hotel (Room No. 6, 2d. floor) and will remain there a few days, where they will be happy to exhibit to the Ladies and Gentlemen of Burlington specimens of their work, and render such other attention as may be necessary for their information.
