John S. Adams, daguerreotype Rooms, No. 115 Court Street, Corner of Sudbury St., Boston. Daguerreotype Miniatures taken at all hours of the day, without regard to the weather—either single or in groups—plain or colored—upon the most favorable terms.  Ladies and gentlemen are invited to call and examine specimens, which for beauty of execution, superior finish and Legibility, cannot be excelled.  In these, every feature is fully brought out and distinctly seen, and the life-like appearance which Miniatures from this establishment assume, cannot fail to give the most perfect satisfaction.

By a new process they undergo, the proprietor is enabled to warrant them to retain their color and not to change in the least by exposure to the air or light.

Daguerreotype Apparatus, Plates, Cases, &c., for sale at low price and warranted.  Instruction for the use given gratis.  March 7. Advertisement ran from March 16 to April 7, 1846.
