The mural shows an inmate escaping from Reading Prison, a disused institution in southern England that once housed Irish poet Oscar Wilde.
His style matches the work of the most enigmatic star in street art, but nothing has yet confirmed that Banksy is behind it.
The mysterious work probably represents Wilde, suspended above the prison wall on sheets of his typewriter.
He was held at the institution, then known as Reading Gaol, for two years from 1895, after being jailed under a landmark law against “gross indecency” used to prosecute homosexuals. Wilde’s 1898 poem “The Reading Prison Ballad” is a reflection on his time there.
The prison closed in 2013.
In December, Banksy confirmed he was behind a new mural in Bristol, the English city many believe to be his hometown.

The mural, which the artist nicknamed “Aachoo !!”, shows an old woman sneezing violently, her dentures flying through the air.
Banksy confirmed the work to be his on his Instagram page, the usual forum he checks for artwork. No other work has been verified since.
But it has been busy for the past year, dropping a handful of works inspired by the pandemic.
The following month, he paid tribute to healthcare workers with an image titled “Game Changer,” which featured a child playing with a nurse doll wearing a mask and cape.
