In 1958 the Korean National Tuberculosis Association would introduce the first multiple seals in the Christmas/TB seal series. There are two seals, each with a hand with a green sprout coming out of the hand. Other than the fact that there were two different seal images, there are few varieties of this seal known to this author.
The 1958 seals were printed by lithograph on un-watermarked paper and sold in sheets of 50 (10 x 5) seals (25 of each of the different designs). The sheets were sold as perforated 12 1/2.
