I think these are really cool--great looking, and potentially useful for all sorts of things, including most immediately for testing one's own visual memory (and capacity to focus!) The set includes extensive instructions for using these as teaching and assessment tools, 48 cards printed in different colors with sequences of geometrical forms, and 12 cards with individual forms in black, intended to ensure that the subject is able to replicate each adequately before embarking on the memory assessment.
The cards, which are of light cardstock weight with glossy finish, are in excellent, like new condition and the colors super bright. Some wear to the box including a stain and "Peterson" written on the front. Box measures 7 7/8" x 4" x 1 1/4".
