North Korea 5-won overprinted 2002 note confirmed

This 5-won note is like Pick 19 with an original date of 1978, but overprinted in black “Sun’s Day, Celebration, 90th Anniversary 15th. 4. Juche 91 (2002)” in honor of the 90th birthday (15.04.2002) of President Kim Il Sung.

Does anyone know if other denominations are available with this overprint, and if this was issued as a commemorative note or as a numismatic product not intended for circulation?
