To promote stamp collecting and to spread the stamp culture, Korea Post has annually designated a "philately week" and held Stamp Exhibition during that week. This year, PHILAKOREA 2009 24th Asian International Stamp Exhibition will be held from July 30th to August 4th, at Indian Hall, COEX.

At this Exhibition, stamp exhibits from about 30 countries will be displayed. Special halls such as "Korea Postal Service Hall" and "Postal IT Hall" will be installed, together with "Postage Stamp Experience Hall" "Philately Class" and "My Own Stamp Corner." Asian children's speech contest, puppet shows, a musical and various other performances designed for children will be presented. There will be both stamp-experiencing events such as stamp dice throwing, looking-for different parts in stamp drawings and stamp cube solving, as well as such education programs as stamp-based cultural heritage exploration, mimicking stamp-collecting, etc. All these events will welcome all family visitors.

This year's special stamp issued to commemorate Philately Week takes the form of a "stamp in a stamp." The stamps introduced as "stamp in a stamp" are definitive stamps issued in May 1900 (worth 1-cheun, Taegeuk and Plum Blossoms) and definitive stamps issued in May 1969 (worth 7-won, National flag, Taegeukgi). They are introduced in a triangle-shaped stamp. The definitive stamp worth 1 cheun is one of the Plum Blossoms (called Ihwa in Korean) definitive stamps is oine of the first stamps to be printed in Korea. The definitive stamp worth 7 won is the first stamp to be printed in Korea using the gravure printer since its introduction in Korea. This special stamp will be a photochromic stamp that reacts to ultraviolet light: such items on the two sides of the stamp as ' ', ' ', ' ' and ' ' will change from dyed color into a red color, when they are exposed to direct sunlight. This special stamp in the form of "stamp in a stamp," which was first introduced in 2007, will continue into its 2010 version.
