We have obtained CCD images in R and V of Malin's “jet” in the weakly radio and X-ray active E0 galaxy M89 (NGC4552). the luminosity of this feature is approximately 1/4% of the total luminosity of the galaxy; its color is bluer than that of the whole galaxy with a V-R value smaller by about 0.15 magnitudes. the likely explanation of the feature, which looks more like a proboscis than a jet, is that it is, in the words of the Toomres (1972), a “tidal relic of a close encounter”, seen from a perspective that may hide a drawn out tail.
