Glorious color. Opening this Color-aid box and flipping through the samples feels like pure luxury to me. Creatively inspiring and useful in many ways, color therapy among them! (Also kindergarten-style paper weaving and folding!) I have not counted but looks to be a complete set of 220 or very nearly so, with papers all in crisp, clean, excellent condition. Original box, with original slip inside, and original cardboards, holding them flat and straight. 1975. 

Box 9 1/4" x 6 1/8" x 1 1/2". Swatches in excellent condition. Light wear and small tear at one corner of the opening top flap, as documented.
