This unusual cabinet card is by William McCrae, art photographer located at Berkeley Road in Dublin, Ireland. His studio was opposite the Mater hospital. He was formerly located at Lafayette. This image features an early motor car and chauffeur. The previous owner of the photograph asserted that this car’s registration plate (ik-29), indicates that the car was from Dublin and the time of the photograph was sometime after 1904, when registration plates were introduced.
