Great images. never seen those before.I'm certain that the painters are members of psych group The Fool.
Thanks Colin,yeah, the couple in the photo with John are Marijke Koger and Simon Posthuma from The Fool,I posted a rare interview with them from 1967 earlier in the year, if you click on the labels just above the comment section it'll take you to it.
