A Banksy-inspired graffiti piece has sparked excitement in Sofia , appearing in the Borisova Garden just steps from the capital’s Kolodrum arena, BGNES reported. The street artwork surfaced recently, with social media users linking its emergence to the Massive Attack concert held on June 29 or shortly thereafter. The piece features a striking image: a man with bloodied feet clutching a bunch of balloons, lifting him off the ground like a hot air balloon, with flames igniting his crotch.
