Image description: This hand colored glass lantern slide is of the rose gardens at “Newmar,” Senator George Almer Newhall house, Hillsborough, California in spring 1917.
A lantern slide is a small glass transparency, typically 3.25 x 4 inches, designed for use in a projector that casts an enlarged image on a wall or screen. This slide was created from a black-and-white photograph taken by noted American photographer Frances Benjamin Johnston (1864-1952). She was a dedicated advocate of the garden beautiful movement in the early 1900s and slides such as this were used to illustrate her popular lectures for garden club members, museum audiences, and horticultural societies from 1915 until the 1930s.
