In 1964 the Korean National Tuberculosis Association (KNTA), following 1961-1963’s examples, would again introduce multiple seals with four different designs in the Christmas and New Year/TB seal series. Unlike in 1963, the KNTA did not use different colors for the different seal designs. All four seals for 1964 have what appears to be a stylized Christmas tree in background, with a drummer on one seal type, a dancer on another seal type, a kite on another type of seal and also a candle on the fourth seal type. These 1964 seals were produced in sheets of 100 (10 x 10). The 1964 seals were printed by lithograph on un-watermarked white paper and the sheets were sold as perforated 12.
The Korean Postage Stamp Catalogue (KPSC) gives the numbers for these 1964 seals as CS35-CS38. The catalog value of the block of four for each set is 10,000 won ($7.70), or 2,500 won ($1.95) each. These 1964 seals were not sold in booklets, but some sheets were broken up as panes of 10 and placed in small envelopes for sales and promotions to customers as in previous years. The 1964 envelope that the panes of 10 were placed in, has written in Korean language a lot of information about the TB program, like the 1962-3 envelopes, both on the outside and inside of the envelope. The English translation of the Korean writing on the envelope is presented later in this article.
