I'm reliably informed that the poster (right) grandly named L'Enfant but more commonly known as Man and Baby wasn't a phenom in the United States like it was in the U.K. Here, it capitalized on the worldwide success of Three Men and a Baby and perfectly captured the sensitive man zeitgeist of the late '80s, becoming one of the country's top-selling posters of all time.
Honestly, I never understood its popularity. Sure, the guy was hunky in that Levi's ad beefcake way, but what was the baby adding? Even as a kid, I associated having children with stress and domesticity; I didn't yet understand that a man caring for his child was considered a novelty.
