September 2, 1952 Marilyn served as Grand Marshall at the Miss America Pageant. 
Playboy founder @HughHefner picked a photo from this parade as the cover of his first then undated December 1953 issue of the magazine.
The parade was held in Atlantic City, Marilyn was on publicity from the studio.  A few months later she would garner her major success with filming ''Gentlemen Prefer Blondes''. Her risque calendar photos broke to the public earlier in '52, then bought by Hefner with a loan his mother gave him to start up the groundbreaking magazine. He entitled her the only ''Sweetheart of the Month''. 

Trivia: The Miss America crowned that year 1952 Colleen Hutchins, died this past March. 

The dress she wore was considered revealing as it was cut close to her navel.
The Playboy cover of MM is actually backwards, Marilyn parted her hair the opposite direction, i flipped the original photo. 
-  Coincidently Hefner was born the same year as Marilyn, as was the Miss America winner of that year.
- Oddly, there's still some people who think Marilyn ''posed'' for Playboy. 
Hefner still credits her though, and will rest next to her for eternity at Westwood Memorial Park. 


Marilyn got to play a pageant girl a bit herself in the movie ''We're Not Married'' released earlier the same year as this parade. 

''A Justice of the Peace had performed weddings a few days before his license was valid. A few years later five couples learn they have never been legally married. Annabel Norris (Marilyn Monroe) already -Mrs.- Mississippi and ready to enter the -Mrs.- America contest, is now free to enter the -Miss- Mississippi contest.'' - Can you say Miss America!
