Carl Sagan was the Space Age genius whose ideas spanned the "Cosmos" – and invited the rest of us along for the ride. Whether you're star-struck or bound for the stars, this is the card for you. Use it to write an overdue thank-you card to your favorite high school science teacher or a starry-eyed love note to your lab partner.
Each die-cut note card comes with a sticker sheet filled with cosmic images and traditional messages like "Happy Birthday" and "Bon Voyage." Envelope included.
