In 1990 the Korean National Tuberculosis Association (KNTA) seal program, for the first time ever, did not produce a large sheet of Christmas/TB seals for a year. Instead they released two souvenir types of sheets with ten images on each of the two sheets. However, one set of five images is on both of the small sheets, while five different seals were used that differed from one another on the two sheets. So there are actually fifteen different images of the seals for 1990. The seals depict the preparations and procession of a traditional Korean wedding.
The 2022 Korea Postage Stamp Catalogue (KPSC) gives the catalogue numbers for the 1990 seals as TCS 248-257 and TCS 258-267, respectively, for the two small sheets. This would indicate that there are twenty different images, but five images are the same on each sheet, so the author does not understand the reasoning of the KPSC for assigning these numbers for the 1990 Christmas/TB seals. The KPSC values each small sheet at 8,000 won (US$6.00).
