Original tape box with tape from Jimi Hendrix's recording studio Electric Lady Studios. Daniel Blumenau in-house artist around the time of the opening, stated that a little know fact was that Jimi had suggested the design of the letters for the studio logo. Much of the design and vibe of the studio was due to Jimi's input while it was being built.

The tape is a 90 second long recording called a "radio spot", an advertisement for radio stations to broadcast, promoting the Rainbow Bridge Movie as it came to their local area . The movie started to be distributed in the Fall of 1971.

1/4" tape, 5" reel at 7-1/2 IPS (speed), cut in Stereo. Audio engineer George Marino (Sterling Sound) and John McDermott (Jimi Hendrix Estate) reviewed this tape circa 2001, determining it was a stereo mix, and was authentic. The tape is in it's original box, and is in undamaged clean condition.
