    The SNR PKS 1209-52 is well known for its symmetrical morphology. It
    also contains a centrally located point X-ray source, 1E 1207.4-5209.
    The ratio of the X-ray to optical luminosity for this source exceeds
    1000.  We argue that the point source must be a pulsar. Inspection of
    the radio image reveal a 15 arcmin nebula surrounding the point
    source.  Its symmetrical location and morphology is highly suggestive
    of a plerion powered by the pulsar. We argue that the SNR issimilar
    to Vela.We predict that X-rays should be detectable from the plerion.
    Using the Einstein data we predict that an ASCA pulse search would be
    quite successful.  Most likely the plerion has been brightened up by
    compression by the reverse shock, a phase that is of some interest
   from a theoretical point of vi
