A close friend of Louis Armstrong for more than a decade, Jack Bradley took thousands of photographs of the jazz great and saved his sound recordings, fan letters  — even handkerchiefs.

Now a small part of his vast collection is featured in a new exhibition at the Louis Armstrong House Museum in Corona, Queens.

Among the highlights is a rare, never-published photo of Armstrong weeks before his death, that shows him at home playing the trumpet along with one of his recordings.

He died in 1971 in the house that’s now the museum.
