Banksy has lost a battle with a greetings card firm over the trademark of one of his most famous works.
North Yorkshire-based Full Colour Black challenged the artist’s right to trademark his image of a protester throwing a bunch of flowers.
The European Union trademark office has thrown out his trademark and accused him of being “inconsistent with honest practices” when trying to protect it.
For a trademark to be valid, the holder must sell goods using the image.
But the authority said he had filed it in order to avoid using copyright laws, which are separate and would have required the famously elusive Bristolian artist to reveal his true identity.
