   We propose 35 ks observations of the Seyfert 2 galaxies Mkn 573 and NGC
   3393. These observations, combined with others in the ASCA archive,
   will complete a flux-limited sample of 7 type 2 Seyfert galaxies
   selected on the basis of the least biased parameter, the [OIII]5007
   line flux. This sample will provide the best feasible basis for
   estimates of the distribution of column density, continuum slope, and
   iron Kalpha equivalent width in Seyfert 2s. These distributions are
   essential for the study of AGN unification schemes, and to evaluate the
   contribution of Seyfert 2s to the X-ray background.
