 The group 's work continued , and the Fine Arts Department established it into an official committee , with ML Pin as chairman , to make preparations for the 100th anniversary of the king 's birth , which would be recognised by UNESCO . ML Pin lobbied for the construction of Vajiravudhanusorn Hall , a museum displaying the king 's works and duties , at the National Library . The hall was opened in 1981 , despite budget problems during construction , which ML Pin had to sell part of the property on Damrongrak Road to help fund .
