Marilyn Monroe cover for ‘Playboy,’ Dec. 1953 (NY Daily News)

“Playboy” creator Hugh Hefner put out the first issue of his influential magazine in December 1953. It featured actress Marilyn Monroe on the cover and centerfold. Hef knew exactly what his mag (originally titled “Stag Party”) was all about: The introduction to Volume 1, Number 1 clearly states that the periodical isn’t a “family magazine.”

Today, this legendary first issue that spawned an empire is up for auction. Put up by Nate D. Sanders in Los Angeles, it’s expected to go for $2.7K. This first issue is very rare, as only around 54K copies were printed since Hefner wasn’t sure if it would be successful. Luckily for him, it took off immediately, and American culture was never the same.
