CCD images and surface photometry for the three dwarf spheroidal companions to M31 are presented. The derived light profiles are used to define the faint end of the surface-brightness-luminosity relation for early-type dwarfs. New structural parameters are computed for a subset of the Galactic dwarf spheroidals, which indicate, when compared to the M31 dwarfs, that both sets of dwarf galaxies are similar. A B - V color is measured for And I and found to be in accordance with that expected from the metallicity derived by Mould and Kristian (1990) from their color-magnitude diagram study. Their claim of a color gradient in this galaxy is ruled out. The metallicity-luminosity relation for E galaxies is investigated using these and other new data. It is suggested that a change in slope occurs between the dwarfs and the more luminous E galaxies.
