These Sesame Street books are great for kids to learn about shapes, letters, numbers, people, and things. Just sit back and read them with your little ones to enjoy a fun learning time. When using these books, be gentle with the pages as they are a bit old. To maintain them, keep them in a dry and cool place. Avoid getting them wet or dirty. If there is some dust on the covers, you can use a soft cloth to gently wipe it off. Have a great time with these vintage books!
