I am by no means a Grateful Dead expert but I am somewhat familiar with them, the first thing that stuck out to me on the poster is that Mickey Hart wasn't present and he seems like the type to get out of his deathbed rather than miss a photo op, so I figured it must have been when he was asked to "voluntarily" leave the band. That was very early 1971, I think he came back in 1974. I looked at their 1970 and 1971 albums to see if that photo was used and I found it, it was the inset photo on their 1971 album 'Grateful Dead Live' AKA Skull & Roses which was a gatefold album, common at that time. The album was released in the fall of 1971, I believe.
