The latest, most beautiful, and permanent method of colouring photographs, termed Ivorytypes. [graphic] : The great advantage of Ivorytype over every other method is its durability, being impervious to water or air. The paper being prepared and cemented on plate glass, the colours cannot possibly fade, and having all the beauty and appearance of the finest ivory painting. They can be taken either from life, daguerreotypes, ambrotypes, or talbotypes. When not taken from life, it is necessary to give the colour of the eyes, hair, and general complexion. Executed in the very best style, on reasonable terms, by James W. Williams, at the artist's emporium, 33 North Sixth St., Philad'a. Where specimens can be seen.
