Rare 2.5 x 4 carte-de-visite photo of President Andrew Johnson in a seated pose, taken by Brady's National Photographic Portrait Galleries of Washington, crisply signed on the mount in ink. In fine condition, with lightly trimmed borders. Johnson's president-era signature is uncommon on its own—he frequently used a stamp due to a crippled right hand—and he is especially scarce in signed photos, this being one of a handful of cartes-de-visite we have offered. Encapsulated in a PSA/DNA authentication holder.
