Detailed spectrophotometry, broad-band imaging and low-resolution two-dimensional spectroscopy of the very luminous "E+A" galaxy discovered by Oegerle, Hill & Hoessel (1991, ApJ, 381, L9) is presented. Among other characteristics, this galaxy has no detectable ongoing star formation; its surface brightness profile follows an r1/4 law, yet it has a faint tidal tail; and its spectral energy distribution can be fit almost perfectly from 3000 Åto 10,000 Åby a pure, 109 year old post-starburst stellar population model. This remarkable galaxy may exemplify the tail end of the Toomre sequence -- the last link in the chain between merging, star-forming spiral galaxies and a single quiescent elliptical.
