This is Poole shape number 699 and is referred to as a Poole peanut vase – because of its peanut shape! It has been decorated with the very modern and stylised PKT pattern designed by Alfred Read back in c1954 and belongs to the range often referred to as Poole Freeform ware. It can be dated c1959-1967.
We also have a bigger version of this Poole freeform vase available – shape number 799, the next size up! This vase has also been decorated in the Alfred Read design PKT but the pottery mark dates slightly earlier, c1955-1959. They make quite a pair – see below!
