Pair of antique composite stone windowboxes

57 long x 18 h x 20cm deep We think these date to the 1960s because we found them when my parents bought the house in 1972 from an elderly lady, Mrs O'Malley. Drainage holes at bottom as you might expect. Lovely either as windowboxes or each placed on top of 2 bricks to make a planter. Sold as a pair.
