Elusive British street artist Banksy has highlighted the issue of rough sleeping in a seasonal mural showing two flying reindeer pulling a homeless man on a street-bench sleigh.
The artwork, created in Banksy's trademark stencilled graffiti style, appeared in Birmingham central England over the weekend.
A video posted on Banksy's Instagram shows a bearded man named Ryan reclining on the bench, echoing the traditional image of Santa on his sleigh.
"God bless Birmingham," Banksy wrote.
"In the 20 minutes we filmed Ryan on this bench, passers-by gave him a hot drink, two chocolate bars and a lighter - without him ever asking for anything."
The video attracted nearly three million views on Instagram in the first 24 hours, and created a buzz in Birmingham.
The two reindeer gained red noses in the hours after the mural was unveiled. A protective fence was in place on Tuesday, stopping any other additions to the design.
Works by Banksy, who has never revealed his identity, have rocketed in value.
A large Banksy painting of chimps sitting in Britain's parliament sold for more than $US12 million ($A18 million) in October, a record price at auction for his work.
Later in the same month, however, Banksy opened his own "online store", selling works for as little as STG10 ($A19) to buyers who were randomly selected and who could answer the question: "Why does art matter?".
