Dr. Seuss has drawn the popular Cat with his big red and white striped hat and red bow on a First Day Cover recognizing butterflies, cancellation postmarked Indianapolis June 6, 1977. The red crayon on the hat and bow is somewhat light. In a speech bubble drawn in black ink and colored in yellow artist's crayon to match the yellow butterfly First Day of Issue stamp, Seuss wrote, my...Best always...Ted!" Under the speech bubble he signed again, "Dr. Seuss." Exceptional with two signatures and especially attractive.
