BBC's Antiques Roadshow expert, Jon Baddeley, halted the show to advise a guest who could be sitting on a fortune. During an episode hosted by Fiona Bruce, Jon urged the guest to take action after revealing that their item could fetch thousands.
The episode, filmed at Clissold Park in North London, saw Jon meet a guest who had brought along a collection of colourful 1960s music posters. Jon noted: "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 revealed: "Because I am that artist, "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."
When asked about his experiences, the guest reminisced: "Yes, it was. I can remember and I'm afraid I indulged a bit too much."
Jon then questioned the guest about two similar but slightly different posters.
The guest on Antiques Roadshow explained: "Well, it was a Blues show. I did this artwork of a complete - Blues musicians at the top, a street scene with people dancing (at the bottom).", reports Leicestershire Live.
Mr Baddeley asked: "But Bill Graham, who ran the Fillmore Auditorium, had had lots of trouble with the police, and he thought that would be provocative," he continued, pointing to an illustration of a policeman on the poster. "So he and the printer changed the poster. But as far as I know, this is the only copy of the original."
He remarked: "When you talk about value... individually these all are in incredibly good condition, they belong to the artist and they're very rare."

Mr Baddeley asked: "So they're gonna be worth £200, £300, £400, £500 - maybe even up to £1,000. But the great value is the one at the end because that is one of one, it's the only one known in the world, so that could be worth £2,000 or £3,000."
He then asked: "And then that went to production and around town?" The guest replied: "And it is still on t-shirts to this day."
He concluded: "But more interestingly, you also own the original artwork so please, please, please go home and see if you can find them because they could be worth many thousands each! ".
