From the National Hellenic Museum Facebook page:

On Saturday, the National Hellenic Museum was filled with the love of Greek history and culture and a tangible reminder of the enduring legacy of Hellenism. Serving as a center for Greek and Greek American culture, the museum was chosen by the University of Illinois and the Consulate General of Greece in Chicago as the site of their celebration to honor the acquisition of a rare early print edition of Plato.
