According to Politico, Johnson gave Biden a framed photograph of a leading 19th-century anti-slavery campaigner Frederick Douglass.
As per the British media reports, Downing Street decided on the photograph after coming across it on the Wikipedia page for Douglass.
The photograph of the anti-slavery campaigner was taken by Melissa Highton -- a UK-US dual national.
Following the meeting between the two leaders, Biden thanked UK PM for hosting him, on Twitter. He said: "The special relationship between the United States and the United Kingdom is stronger than ever."
Meanwhile, Johnson also affirmed the strong US-UK ties, saying, "The future of the world's stability and prosperity lies in cooperation between the UK and the US, the closest of partners and the greatest of allies."
