No instructions. came with these vintage "Configuration Cards," produced by Teaching Resources (an educational service of the New York Times, notes the box) in 1967, and I have not found another set out there, but I assume they were used for testing and teaching the ability to translate the number and color of dots on the cards into language, as well as for teaching matching and sequence. Part of what I love about them is indeed how open ended they are to application to all sorts of learning exercises and challenges (and made-up games I think, too), but most of all I just love the look of them! (I keep thinking of Lichtenstein's ben-day dots when I look at them, with their great black borders like frames around paintings.) Surely inspiration and/or material for all sorts of creative endeavors.
108 cards total, detailed on the inside of the box, which once belonged to the Reading Lab at Illinois State University. The cards, very nicely produced and of substantial weight cardstock, are in excellent condition. The box shows some wear and tape on the sides but is structurally in great shape. Box measures 9 1/2" x 4 3/8" x 7/8". Cards are 4 1/16" x 3 1/16".
