Slab of likely 1960s concretion with brown tiles, probably from a wall but could be floor. Posed in my hand on the Thames Foreshore at low tide, the Shard and London Bridge in the distance.
Yeah. Not a slab of chocolate but concretion with brown tiles, and definitely has a 1960s interior décor look, if you ask me. The river has forever been used as a dustbin for building rubble, whether Roman or from the modern era #Mudlark #ThamesForeshore
