For your consideration, here is a 1989 Kellogg's Cereal Crayola Color and Activity Book Promotional Insert, with Coupons. The coupons on the back have a copyright date of 1989. Two coupons have no expiration date, one expired in 1990 and the other two expired in 1989.

It is in nice shape, with no creases in the book. The plastic bag has not been opened, but there is some wear on it. This will be mailed in a box.  Item pictured is the actual item up for sale, and comes from a non-smoking household. (110.997b-.10hc)
