A near-infrared photographic atlas of 54 spiral galaxies is presented. Blue photographs are included so that features may be compared in the two passbands. Hubble types range from Sa through Sd for SA, SAB, and SB galaxies. Most are nearly face-on and larger than 2 arcmin. These galaxies have been subdivided into the subjective categories of grand design and flocculent spirals, depending upon the appearance of their spiral arms. Photographic procedures and their effects are discussed.
