In 1983 the Korean National Tuberculosis Association (KNTA) seal program used a special design for the 1983 Christmas and TB seals with a different type of layout. The KNTA honoured the 30th anniversary of the when the KNTA took over the program and produced its first seals in 1953. A set of ten seals was issued with an attractive strip of ten showing nine different Korean animals and one of a seal from 1953. The seals were printed in sheets of fifty seals, with one complete set of ten running horizontally across the sheet. So each sheet contains five complete sets of the 1983 seals and five vertical rows of each different seal.
The 1983 Christmas/TB seals were only issued in sheets of fifty seals, and no souvenir sheet, booklets or postcards were issued in 1983. There was a special 30th anniversary presentation book that was issued, said to be 500 copies distributed. The author has not seen one of these.
The 2022 Korea Postage Stamp Catalogue (KPSC) gives the catalogue numbers for the 1983 seals as KPSC TCS 166-175. The KPSC values the set of ten seals at 15,000 won (US$10.75).
In 1983, the production by the KNTA of the seals continued to increase over the previous year to an amount of 15,225,000 seals. The seals for 1983 were completely sold out. The price of each seal was also increased from 50 won to 60 won. As a result of the increased sales and increased value of each seal, the funds generated by seal sales for 1983 for fighting TB by the KNTA set a record amount.
The author has seen two different types of the sheets of fifty seals of TCS 166-175. There are two different types of perforations for the sheets. For Type 1, the perforations go all the way through the top margins. For Type 2, the perforations go all the way through the bottom margin.
As in previous years, the Christmas/TB seals, were distributed by posting in the mail/handing out to customers in envelopes, with a folder inside the envelope that contained the seals in a pocket in which the seals are placed. The KNTA introduced a textured envelope for the seals in 1983.
This set should have been issued as postage stamps, rather than seals.
South Korea has issued a few series of birds, butterflies and marine fauna, but no independent set of the mammals.
