This delicate surface pattern is known as Beaded. The pots are by Hornsea Pottery. The graphic designer, I think, is Jack Dadd. The range is from the early 1970s.
To me, the design has a wonderful lace-like quality and the black linework on the ivory-coloured background looks clean and bold. The look is further enhanced by the slight irregularities that occur in the hand-drawn design.
I understand that the range was not a good seller for Hornsea. It's a pity. Because I think this is a design that deserves a closer look.
I found another example of Jack Dadd's work in the V&A museum. You can see it here Jack Dadd mug
