Fortunately Greg Chinn has your back. This Art Director/Dad created a whimsically-designed set of flash cards for his daughter that happen to hold wider appeal. Not a surprise: a mini feast of terms and iconic images from the era is packed into each 2 3/4" x 2 3/4" card.
Greg e-mailed us about the set the other day:
"I've created some Mid-Century Modern Alphabet Flashcards that may be of interest. You can purchase them at the Cooper-Hewitt Design Museum and the San Francisco Museum of Modern Art."
And also through Greg's website.
The set is $30 (includes $5 for shipping and handling).
