Based on png version Image:4 Vesta Unsimplified Symbol.png

Early papers for Vesta use a more complicated symbol more-or-less as shown here (at that time, it would have been individually drawn by each person using it).  Based on Gould, B.A. 1852, On the Symbolic Notation of the Asteroids, Astron. J., 2, 80, and partially created from Image:Vesta symbol.svg, also released to public domain.
