The New York World's Fair 1964-1965 was opened to the public in New York beginning April 22, 1964. The basic purpose of the Fair was 〝Peace through Understanding.〞 As our country was invited to participate in the Fair, a Pavilion of the Republic of China was established. To mark this memorable occasion, a set of commemorative postage stamps was issued. The 0.80 stamp shows a unisphere, emblem of the Fair, above which are the national flags of the U.S.A. and the Republic of China. The 5.00 stamp takes the China Pavilion, a palace-style building in the Fair, as its subject matter. The unisphere emblem of the Fair is in the upper left of the design. The 2.00 stamp has the unisphere, emblem of the Fair, in the left part of the design and a distant view of the China Pavilion, a palace-style building, on the right. The 10.00 stamp uses a picture entitled 〝100 birds paying tribute to queen phoenix〞 as the design with the unisphere emblem inscribed at the upper right corner.A carved wood screen with a similar design as the 10.00 stamp, which symbolizes visitors coming from all over the world to see the New York World's Fair, was displayed in the China Pavilion.　　The above-mentioned 0.80 and 2.00 stamps were originally scheduled for release on August 24, 1964. But due to delay in sea conveyance, the date of issue was postponed to September 10.
