yes, it looks like the 80s/90s bottle, but the green at the bottom would be local.
In the lead-in to introducing the draught in the early years 90s, there were changes to the US version of the extra stout, and in the transition, some shipped with yeast at the bottom (which I believe was the norm in the UK at the time).
Anyway, a friend cultured it and gave some to me. I got a couple of good batches of stout and pale ale from it, before that starter went bad. I forget what happened to the part I had in the freezer with glycerin.
