Kristofferson played it for Joplin during the time he was Joplin's live-in boyfriend near the end of her life. Joplin's version of the song became a #1 song in 1971, after her death (the second posthumous #1 song in history, after Otis Redding's Sitting on the Dock of the Bay).
My other Hendrix custom is a copy of his Monterey Strat - with the daisy on top, not the rose as Pamelina (incorrectly) painted for the Strat reissues.
