We present BVRI surface photometry of spiral galaxies suitable for the absolute calibration of the Tully-Fisher relation. Galaxies were observed at the Fred L. Whipple Observatory (FLWO) 1.2 m, the Mount Stromlo and Siding Spring Observatory (MSSSO) 1 m, and the Cerro Tololo Inter-American Observatory (CTIO) 1.5 m telescopes from 1994 to 1999. The surface photometry measurements were carried out using the SFOTO package. We also present new derivations of 20% and 50% 21 cm line widths for most of these galaxies, based on existing profiles.
