Happy birthday Mr. President! This is the complete set of Marilyn Monroe’s “Red Velvet Collection autographed by Tom Kelley, the photographer of this series. There are only 30 sets of this series in existence, and Kelley has signed and numbered each of the photos in this set, validating the $5,000 starting bid.  

Monroe is the original calendar girl, and at 22 years old, these nude photos show how the advent of the calendar girl gained such momentum. In fact, it was one of these photos that launched Hugh Hefner’s Playboy magazine in 1953.

Love the ladies, or just have a crush on one of the all-time greatest pinups, either way, you’ll want to click through and check out the pics.
