Leo Durocher managed the Giants to a World Series title and pitched sugary cereal to kids! Mastro offered this one in their November 2001 catalog.

Here’s the full item description from the catalog:
In the early 1950’s, Leo Durocher managed the New York Giants to two pennants and a World Championship. During those exciting years, the feisty and popular Durocher endorsed a variety of products, and Madison Avenue saw fit to use his image on this store display advertisement for the Sugar Crisp Cereal Baseball Facts and Fun Book. The offered display ad shows a beaming Leo the Lip with his Giants cap on, encouraging youngsters to eat Sugar Crisp. The display is printed on sturdy advertising stock cardboard and is in Near Mint to Mint condition with the exception of some very light creasing to each of the four corners. The sign has never been used and is quite rare, especially in this exceptional condition. In retrospect, all that sugar may help to explain the many tantrums for which Durocher was so well known. An attractive and very colorful 1950’s advertising sign featuring one of the game’s most memorable managers. Measures an impressive 23” x 28”
Minimum Bid $300
In September 2004, Heritage sold a copy of this display for $489.95 but noted it measured 20″ x 31″ at its greatest dimensions and dated it to 1954.

In the Fall of 2024, REA sold a framed copy for $330, approximating its release to 1955.

You can pick up copies of the Post Sugar Crisp Baseball Facts and Fun Book for ~$45 on eBay, where most copies are dated to 1954.

Happy collecting!
