Antiques Roadshow expert demands guest 'go home' after making discovery

BBC's Antiques Roadshow expert, Jon Baddeley, brought the show to a standstill to advise a guest he could be sitting on a small fortune. During an episode presented by Fiona Bruce, Jon encouraged the guest to take action after revealing that their item could rake in thousands.

The episode, shot at Clissold Park in North London, saw Jon meet a guest who had brought along a collection of vibrant 1960s music posters. Jon observed: "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 disclosed: "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 fondly recalled: "Yes, it was. I can remember and I'm afraid I indulged a bit too much."

Jon then probed the guest about two similar but slightly different posters, reports . The guest on clarified: "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)."

The antique guru queried: "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, indicating an illustration of a policeman on the poster. "So he and the printer altered the poster. But as far as I know, this is the only copy of the original."

He commented: "When you talk about value... individually these all are in incredibly good condition, they belong to the artist and they're very rare."

Jon continued to question: "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 , so that could be worth £2,000 or £3,000."

"And then that went to production and around town?" quizzed the expert, only for the guest to respond: "And it is still on t-shirts to this day."

He concluded: "But more interestingly, you also own the original artwork." He then paused the valuation as he implored: "Please, please, please go home and see if you can find them because they could be worth many thousands each."
