The BBC specialist spoke out on a recent episode of the programme, hosted by Fiona Bruce.

Expert Jon Baddeley encouraged one guest to take action, acknowledging that they could potentially be missing out on a significant sum of money. During a visit to Clissold Park in North London, Jon met a guest who showcased a collection of vibrant music posters from the 1960s. Jon queried: "So you've kindly brought us today a collection of psychedelic rock 'n' roll posters.

What I notice immediately is they're all signed by the same artist, how so?" The guest responded: "Because I am that artist, adding: "So I grew up just north of San Francisco and I was about 19 when I went to work for the Fillmore Auditorium, and some of these posters were for them." Mr Baddeley asked: "What was it like out there? I mean, it must've been really exciting. That was the centre for 'Hippydom', flower power.

.." The guest replied: "Yes, it was.

I can remember and I'm afraid I indulged a bit too.
