The National Film Theatre was a well-known cinema in London, tied to the British Film Institute, where people watched old films, films from many countries, and special seasons — not only new Hollywood movies. It stood on the South Bank of the Thames. The same place was later renamed BFI Southbank, but older British books, tickets, and signs still say the NFT or the National Film Theatre. It is a proper name, mainly UK cultural English. You would not use these letters this way in Taiwan tech talk, and it is not a kind of artwork you buy online.

英國國家電影院（倫敦；後多稱 BFI Southbank）。台灣現在說 NFT，幾乎都是指加密貨幣那一種，那是另一個意思。
