The museum said Janie Hendrix brought a colorful patchwork full-length leather coat, a leather necklace and a leather pouch to be shown in "Up Where We Belong: Native Musicians in Popular Culture," which is to open July 1.
"These are among the very few of the rock legend's possessions sent home to his family from his apartment in New York after he died on Sept. 18, 1970. Though Hendrix's father asked that all of his son's belongings be sent home to Seattle, including 100 guitars, scant few arrived," the Smithsonian said in a news release Wednesday.
"The coat is the signature piece in the upcoming exhibition ... (which) examines Native people who have been active participants in contemporary music for nearly a century. Hendrix's grandmother was Cherokee and his family continues to recognize and honor this heritage to this day. The exhibition will show how his identity contributed to his artistry and how he in turn influenced a whole generation of musicians -- including some of the biggest acts in rock 'n' roll."
