Steve at Principle 5 just pointed out this leaflet on their site, it’s from the now defunct archive.coop, a 10 page colour A4 history of Workers’ Co-operatives 1970s-1990s:
Worker-Co-ops-Learning-Resource.pdf (3.1 MB)
I’m posting it here in case anyone needs something to print for a stall or some slides for a talk or whatever 
.
The archive.coop site appears to have last been online in 2019, it’s worth a browse at the Internet Archive.
The PDF includes photos from this album:
Which is part of the Co-operative Heritage Trust Archive user account uploads on flickr:
Which includes photos from Claverts, 8th Day, Unicorn Grocery, Suma, News from Nowhere and others!
