A subset of the 10 color system of Faber was used to measure absorption line strength (LS) and colors of five SO galaxies, two ellipticals and three globular clusters. These observations are combined with those of Faber and others in order to analyze the LS and color variations among old stellar populations. Two-dimensional photographic surface photometry is presented for 18 SO's and one elliptical, NGC 3379. Isophotal maps and major and minor axis profiles are given for these galaxies. The major axis luminosity profiles of 12 SO's are decomposed into an exponential disk and an R to the 1/4 power law bulge. Previous methods of determining the disk to bulge ratio of galaxies are critically examined and two methods are introduced. The light distribution perpendicular to the major axes of five edge-on SO's are presented.
