My concept is Hangul Proclamation Day known as Korean alphabet day. I particularly focus on and designed from one of the greatest results of the creation of Hangul, which 

is the freedom of expression. Before Hangul was born, many lower-class Koreans were illiterate but they became able to express things that they could not express before in written words by the birth of Hangul.

On the cover, the type says Hangul that is designed by original Korean letters. The 3D typo design implied the illiterate Koreans’ feelings after they could read and write as a result of Hangul.
