After keeping them in his private archive for 45 years, photographer Len Steckler is selling previously unseen shots of Marilyn Monroe lounging around a New York City apartment with the poet Carl Sandburg, NY Post reports.

In the photos, taken nine months before Monroe’s death, the actress and fashion icon is 35-years old. Sandburg is 83. According to the Post, Steckler said, “As we know, Marilyn loved older men; she loved intellectuals — and Carl was very parental with her … It was a lovely thing to see.”

He also said that after the shoot, the three of them drank Jack Daniel’s.

Four single images and two triptychs are priced between $1,999 -$3,999.
