1844 - Lithograph of Daniel O’Connell, based on a daguerreotype

As the daguerreotype process creates only one unique image, it was not easy to make multiple copies. One could take a daguerreotype of the original but this was expensive and not easy to produce in large quantities. For this, lithography or engraving was used, as in this portrait of Daniel O’Connell engraved by Johann Stadler and printed in Vienna.
