In 1968 the Korean National Tuberculosis Association (KNTA) went with two different designs for a pair of seals for the Christmas and New Year/TB seals series. One stylize design appears to be of a child playing a horn on the back of a chicken with two chicks, and the other stylized design depicts a child playing a flute on the back of a flying crane. Perhaps these designs represent some symbol or stories that are popular in Korea and if any readers know about these images, please send the information to the Korea Stamp Society. This pair of 1968 seals was produced in sheets of 50 (10 x 5) with 25 of each set of design per sheet. The 1968 seals were printed by lithograph on un-watermarked white paper and the sheets were sold as perforated 12 ½.
The Korean Postage Stamp Catalogue (KPSC) gives the numbers for the 1968 pair of seals as CS49-50. The catalog value of the pair of seals is 3000 won ($2.30), or 1,000 won ($1.15 each).
