  Cluster ellipticals are often thought to be among the oldest galaxies in the
universe, with the bulk of their stellar mass formed at early cosmic epochs. I
review recent observations of color evolution in early-type cluster galaxies at
high redshift, which show remarkably little change in the color-magnitude
relation out to z = 1. Spectra of elliptical galaxies from 1.15 < z < 1.41
demonstrate the presence of a dominant old stellar population even at these
large lookback times, although there is some evidence for a tail of later star
formation. The Kormendy relation, a photometric/morphological scaling law for
elliptical galaxies, is used to extend fundamental plane investigations to z =
1.2 and to test for luminosity evolution. While the evidence, overall, is
consistent with simple and mild passive evolution, I review some caveats and
briefly consider the data in the light of hierarchical galaxy formation models.
