When I first met Professor Young he gave all his students a photo card that showed his four styles of Calligraphy that he wrote for America’s Bicentennial Celebration.
The calligraphy below is Professor Young’s copy of the famous Lan Ting poem by the King of Chinese Calligraphy (cursive or Running Style): Wang Hsi-ChihImage # 2. 
Below is a couplet that Professor Young wrote in his favorite style: Official Style
