I was struggling for a symbol to represent the traditional Korean Shamanistic beliefs (slightly similar to Japanese Shinto) and I found this public domain image of a mask provided by user Vassil (on Wikimedia) I synthesized it here in the hopes of having something to represent this belief system.
Korean Shaman Mask free icon was designed by j4p4n for icons Png and presented to its users.
