Reconstructed images of the asteroid 4 Vesta reveal dark and bright patterns which can be followed across the disk as the asteroid rotates. We find reasonable agreement with its visible lightcurve by assigning relative albedo 0 to the three darkest features and relative albedo 2 to the three brightest features. From power spectrum analysis of sets of images at two different epochs we obtain Vesta's triaxial principal diameters, the orientation of its pole, and its rotational rate and sense. The images confirm the dominant role of surface structure, particularly the dark spots, in determining vesta's lightcurve signature.
