This piece was recently offered on eBay as an authentic Jimi Hendrix letter and supposedly sold for $10K. It reads in part:

“…at the moment we are still on tthe [sic] tour bus”

“groovy hump cat [sic]”

The seller also provided provenance in the form of a response regarding the letter from Bonnie Bramlett of the 60’s group Delaney & Bonnie and Friends.
