Hodgkins expert Ms Kisler studied the painting.
“You can read Robjn’s painting as fitting in to a really large number of Hodgkins’s works. When you lay those works side-by-side you can see absolutely that Robjn’s work fits among them,” she said.
Mr Cantus said he was “ecstatic” to hear her verdict.
“I do wonder if this is October Landscape,” said Ms Kisler, referring to a painting by Hodgkins that had not been found.
“I think it’s a damn good one – I’d love to have it myself.”
Art expert Philip Mould, who co-presents the BBC programme with Fiona Bruce, said Ms Kisler’s verification was “unquestioningly justifying that valuation of £40,000 to £50,000 but also, as a result of this endorsement, it’s a picture that hereon will be seen and admired”.
