I'd guess this color wheel was completed by an art student as part of a color theory class--and just beautifully executed, I can't imagine that it didn't earn them an A++. Below the large painted color wheel (with initials of colors in pencil around its perimeter) are three smaller wheels highlighting examples of complementary, monochromatic, and analogous color groups. Definitely worthy of framing and hanging!
Executed on sturdy cardstock/board, and in very good vintage condition. There's a little wear around the edges and corners of the board; the color remains super vivid. 14" tall x 10" wide.
