Suggested to be by Banksy by some, but see extract below ....
"Yet, further searching has revealed the piece to be the work of local brasserie owner, Vincent Brillant, and his artist friend Guillaume Debout (aka “Hum Bub Hub”). The work shows his two young girls - aged four and eight - and was created to spread a message of peace.
Speaking
to news source France3, Mr Brillant refuted comparisons with Banksy. He said: “That is just untrue. [Banksy] is artistically extraordinary."
He said: “Where Banksy is strong, is that there is always a message. A sharp message, that is never vulgar, and always controversial.”
The artwork was actually created in 2014, to mark the 70th anniversary of D-Day, and was inspired by conversations between Mr Brillant and British war veterans - many of whom had come to have a drink in the brasserie during the anniversary period.
Mr Brillant explained that the art had been printed onto aluminium sheets, due to a “lack of time”, and had only been intended to last a short while.
He said: “I thought that it would last two weeks at the most [but] the message ‘no more war’ is still relevant.”
His wife, Elodie Brillant,
said: “It is unbelievable to see the number of people from all over the world who have come to take their photo in front of the wall.""
