Flash of Brilliance flashcards have many special features that improve on the traditional alphabet flashcard. The entire alphabet is represented in sign language as well as in written form. Cards are rich in sights and sounds associated with each letter. Clear, expressive photographs show your child how to form the letter in sign language. Learning is reinforced with full-color photographs of real objects, not cartoons. Cards are thick and durable—children love to play with them again and again. Ages 1+
