Mad Magazine Help

I am writing a book on "Cracked" magazine and one of the interview subjects was Paul Laikin, who has worked for every black and white humor magazine over the years, being editor for many of them, too, including "Cracked", "Sick" and "Wacko". Anyway, Laikin was the first of two writers hired by "Mad" after Harvey Kurtzman left with the staff. New editor Al Feldstein placed an ad in the "New York Times" in 1956-57 for new writers and two respondees were hired: Laikin and Frank Jacobs. Laikin stayed with "Mad" until about 1959 and Jacobs is still there to this day.

What I need is a copy of this help wanted ad. Please let me know if you have access to a copy.
