Finally found: The elusive WCF # 751 release:
Matrix : 751 SIDE I / 751 SIDE II
This was the first of three times WCF would release this material, ca. 1972
Source: Radio broadcast from the Winterland in San Francisco on 04 October 1970, the night Janis Joplin dies. This was a joint Quadrophonic broadcast on two radio stations, KSAN and KQED, which also did a video feed on its TV channel. There are claims that the bootlegs contain only half the mix as they only contain one of the two feeds but I did not find that to be the case (compare below).
SIDE 1>Sugar Magnolia/Good Lovin’
SIDE 2>end of China Cat>I Know You Rider/Casey Jones/Uncle John’s Band

It appears that the original version was first released by an independent bootlegger – not TMOQ – who had come up with the mammary presentations logo. These are easily identifiable by their “Mother” labels:
The matrix numbers were either only DEAD-1 / DEAD-2 or:
TMOQ then “took over” this release and first pressed it ca. April of 1972 on colored vinyl and with 1 / 2 labels, giving it the matrix that had been the identifier on the Mother Records label: MEL – 77 A / B:
For the early pressings, I have only seen it with two ringed 1 / 2 or blank white labels. The earliest version of the insert had an intricate background image that was not always present in subsequent versions. Also notice the other differences shown here: Just the drawing, with added text, or both plus TMOQ logo.
Below: Later versions.
TMOQ then must have decided they liked the logo mammary presentations and continued using it on occasion. This is a list of all TMOQ titles bearing that logo. No originals issued by other labels for MM6 onward seems to exist.
MM4 – GRATEFUL DEAD – RECORDED LIVE IN CONCERT (# 71037)
MM6 – JEFFERSON AIRPLANE – TAPES FROM THE MOTHERSHIP (# 71038)
MM8 – THE MOODY BLUES – ANSWER TO THE MYSTERY OF LIFE (# 71053)
MM11 – THE KINKS – WINTER LAND 02/77
JETHRO TULL – NOTHING IS EASY (# 71030)
BUFFALO SPRINGFIELD – “BLUEBIRD ROOTS” (# 71035, copy of the 5D Records title)
LED ZEPPELIN – GOING TO CALIFORNIA (# 72004)
PINK FLOYD – OMAY YAD (# 71049, April 1972)
Contraband copied this title as well but unlike WCF they did care to brand the insert with their own (sub) label name. However, in order to cover all of TMOQ’s mammary productions logo they had to increase theirs in size. That, plus their decision not to clarify with an added ‘Records/Productions’, led to the album being called Shalom to this day.
Matrix: GD 1020 A / B
Based on that number, the release date would be mid-1974, sandwiched between the Beatles albums supertracks 2 (# 1018) and soldier of love (# 1022).
However, Contraband’s sole other Grateful Dead release high time in old town is also supposed to have a 1020 matrix. As this matrix seems to be confirmed, I am waiting for confirmation on what the actual matrix for high time in old town is. If you know, please leave a comment.
In 1973, WCF re-issued this album as part of their 22XX Grateful Dead series from new pressing plates now marked 2266.
2222 GRATEFUL DEAD – Turn On Your Love Light
2233 GRATEFUL DEAD – “Central Park, Fillmore East, Action House”
2244 GRATEFUL DEAD – Sugaree
2255 GRATEFUL DEAD – DARK STAR
2266 GRATEFUL DEAD – “Sugar Magnolia”
And a final time for WCF (I have not seen this reissued with a b&w cover) ca. 1974/5 in a printed folder-style cover and with blank white labels:
