Happy 90th birthday to cartoonist Jack Davis, best known for his work at MAD Magazine. Our Collector's Treasure of the Day is this original pencil drawing by Davis for a print ad done for Group W's news service. Group W is an alternate name for the Westinghouse Broadcasting Company. The firm hired Davis to design several print ads for them, among them this one depicting a man nervously looking at his watch near a train track. A copy of the final ad is included, featuring the tagline "The commuter's best friend". Approximately 7 x 9 inches. Fine condition. Authenticity guaranteed for life.
