Jasper Johns's Flags I (1973), an iconic print by the American artist, has been gifted to the British Museum by New York-based collectors Johanna and Leslie Garfield, reports the Guardian.

The piece was exhibited in the British Museum's American Dream exhibition of 2017. It is one of the most valuable modern prints ever donated to the museum, and valued at around $1 million, according to the Guardian.

“This is a hugely important print,” said Catherine Daunt, a curator of modern and contemporary art, to the Guardian. “It is beautiful, complex and technically a great achievement. We now have 16 works by Johns in the collection, all of which are outstanding in their own way, but visually this is undoubtedly the most spectacular.”

Johns, 90, has been using the flag motif since the 1950s in his work. The artist has said the imagery is up to interpretation, but to him it is just a flag.

British Museum director Hartwig Fischer, said: “American art, like American politics, has always had an influence far beyond the borders of the USA."
