Vintage 1960s set of division flash cards by Ideal School Supply Company, No. 7239. Includes a large number of cards, many with a classic typeface and layout used in mid-century classroom tools. There appears to be some extra cards (the darker ones) from a different box. Cards are labeled as for 4th grade and show some typical aging and discoloration. Outer box has surface wear, some spotting, and corner wear, but remains intact. Great for homeschooling!
