A new Banksy piece disappeared within a day of being revealed.

Adding more mystery to his mythos, street artist Banksy posted a photo of a road sign he had created on his Instagram page Friday, but when fans went to check out the instillation in Clevedon, north Somerset, it had already vanished. Last seen Friday evening, it is unclear whether the sign, which features two elderly people perched on the shoulders of two children, was removed by the artist or stolen.
