Geometric Forms Color Study Vintage Watercolor brass hedgehog I've tried to weed outThis is the smaller of two abstract vintage watercolors I'm listing by the same unknown artist, I'd guess likely done as art school exercises, though I am not entirely certain. They've both got a bit of a Hilma af Klint vibe, this one with a more dense and saturated concentration of elongated triangular forms, transforming in color as they cross the outlined borders of the round forms. Luminous, it keeps making me think of a stained glass window.
