About 100 drawings, dated from the XIV to the XX century, are presented at the exhibition of masterpieces at The national gallery of art in Washington. It is devoted to one of the greatest scholars of the last century, Ian Vulnera. Two key exhibit is the biggest acquisition of Jan Vulnera, known as the "crown jewels": the "Libro de' Disegni" Giorgio Vasari ( probably after 1480-1504) and "Satyr" (1544/1545) by Benvenuto Cellini. The earliest works in the exhibition are two rare sheets from the XIV century: pages from the book of the unknown Austrian artist, and another attributed to the artist Paduani Antihero da Zevio, which depicts a group of knights storming a medieval castle.
