The Design Deck
Each of the 52 faces contains a useful piece of information about graphic design, including typography, colour theory, design techniques, history, and more, with beautiful visual examples.
Printed in rich, full colour on high-quality Bicycle® stock with air-cushion finish.
Very cool idea. These cards were sold out when I last checked the site, but they appear to have stocked back up. Act fast and get a deck for $20 at Forrest Goods.
