I painted a parody of Yatterman using Hidden Art, which is a hidden painting using a light-storing pigment that I invented. You can see the hidden paintings in the dark at the official website of Japanese painter Kozo Sato without any modification. https://kozo.sato.art #hiddenart #蓄光顔料を使った隠し絵画 #これがこう #trickart #illusionart #eroticart #japaneseart
