The overlapping spiral galaxies UGC 2942 and UGC 2943, in a color-composite
CCD image taken with the Cerro Tololo 1.5-meter telescope. The blue
disk colors are clear, as is the reddening by dust across the center of
the more edge-on UGC 2943. The foreground galaxy is not completely
opaque, since the dust lane in the background galaxy can be traced across
the overlap region. The data were obtained by W. Keel and W. White, III.
