A site you may want to visit is the one by Roman Hryciw, which commemorates prominent Ukrainian Professor Stepan Timoshenko, who taught at the Kyiv Polytechnical Institute, the University of Michigan, and Stanford University.
A beautiful web site that deals with the entire spectrum of Ukrainian art and culture may be found at ArtUkraine. Morgan Williams, another of the society's post card specialists, created this site, which features pages devoted to all aspects of Ukrainian art as well as to philately and numismatics.
