5 years ago, Mr. Tan realized his warehouse was filling. He needed more space. 30 years of buying art pieces meant more and more storage space had to be acquired but in the end, perhaps it was time to go through the collection and focus on his particular interest in post-war Nanyang painters. So he finally began to auction or sell off some of his collection.
