Joh (old person) masks depict an elderly man with tied up hair.
The thin shape and prominent cheekbones express age even though it possesses remarkably healthy teeth.
Joh masks can be classified into two types depending on
if it has only upper teeth or both upper and lower teeth,
and if the eyebrows and mustache are drawn on by brush or attached directly to the mask.
Each type of this mask has a different character.
