Korea Post under the Ministry of Science and ICT said on Monday it will issue 450,000 stamps on Nov. 4 to mark the 100th anniversary of the release of the Korean Braille system Hunmaengjeongeum.

Hunmaengjeongeum is a six-dot Korean Braille created by Songam Park Du-seong (박두성), who is called the "King Sejong of people with visual impairments". It combines six dots to express consonants and vowels, numbers and other characters. It is based on principles that it should be easy to learn, use fewer dots and avoid confusion.

Park devoted his life to education so that people with visual impairments could gain knowledge and information through writing. Hunmaengjeongeum, which he created, has for the past 100 years been an important foundation supporting learning and social independence for people with visual impairments.

The commemorative stamps depict Park's portrait using dots, a basic formative element of Braille. They are meant to reflect that Hunmaengjeongeum became a path to learning for people with visual impairments through the way dots come together to form letters.

Korea Post chief Park In-hwan (박인환) said the stamps reflect Park Du-seong's belief that anyone, regardless of disability, can share knowledge and information and communicate through writing. He said he hopes the issuance will help widely publicise the historical significance of Hunmaengjeongeum.

The commemorative stamps can be purchased at nearby main post offices or through the Internet Post Office.
