Chew Chew Baby: Push Pin Graphic No. 53, created in 1967. 10.75" x 7.5". Designed by Seymour Chwast. 12 pages including cover. The text is about the ideas of Horace Fletcher, a 19th Century advocate for the health benefits of proper and thorough mastication. It is quoted from "The Nuts Among the Berries" by Ronald M. Deutsch, 1961. I have only one copy of this booklet. I acquired it in the late sixties. Shipping in the US included.
