Images now uploaded. My copy was pressed by RCA in Indianapolis, and the RCA matrices on the labels suggest that this was mastered (or maybe even pressed) in 1969, so the reason for the delayed release until March 1970 is unknown (I would guess either a symptom of GRT's purchase of Chess in '69, and/or Etta's state of health at the time). It looks like RCA Indy still had a supply of labels saying "Chess Producing Corp." to use up!
Released for digital download and streaming by Geffen/Universal on 27th April 2018. For some reason, the download sites are showing the original release date as 2 September 1969, which is impossible if the album was recorded in November of that year!
The only prior CD reissue of the entire album seems to have been in Japan in 2014, otherwise 8 out of the 11 tracks have been on various reissues and compilations, including the Ace/Kent CD's from the early 2010's.
