The VLA has been used in its most compact D- and C/D-configurations to make low-resolution 1.49 GHz maps of the spiral galaxies north of delta = -45 deg and brighter than B(T) = +12, the completeness limit of the Revised Shapley-Ames Catalog. Most of these maps are confusion-limited at sigma = 0.1 mJy or greater per beam, and at least 94 percent of the galaxies were detected with S = 1 mJy or greater. The maps have sufficient sensitivity to low-brightness emission that accurate radio 'photometry' is possible. An atlas of contour maps, a table of total flux densities plus other radio source parameters, and references to published radio maps are given.
