Sesame Workshop has signed a new licensing agreement that brings personalized letters to small fans of Sesame Street, according to a statement. The “Sesame Street Giftventure” line provides poster-sized letters with a personal game or puzzle for children ages 2 to 5. Solving the puzzle provides the location of a gift the parent has hidden. Big Bird, Elmo, Cookie Monster and Abby Cadabby each appear with a unique storyline and educational games. The $19.95 Giftventures are now available at Giftventure.com and store.sesameworkshop.org.
