Brutalist Architectural Abstract Sculptures. 1960s

Two interesting sculptures made in the 1960s/1970s. They appear to be made from from unglazed white ceramic. The artist is unknown but they have a clear architectural or Brutalist quality. Minor signs of age and use. The square one is 27 X 12.5 X 29cm high. The vertical one is 15.5 X 13.5 X 40.5cm high.
