May 2, 1988 is the date that Amazon US has for this, and I'll accept that in the absence of any other source - Universal's website no longer has this listed, and the closest that Schwann gives me is July 1988, presumably being the issue where it was first listed. This would have been one of the reissues to commemorate the 25th anniversary (on March 5th) of Patsy's death, and I seem to recall that MCA gave all those Patsy reissues new covers, but went back to the original covers (like this one) later.
