Jasper ware cameos or portrait medallions made by Josiah Wedgwood and Sons, at Etruruia in Staffordshire.
They feature profile portraits of John Wesley based on an original design from when Wesley sat for Enoch Wood.
The first two examples are in the more typical blue jasper ware.
The framed oval green jasper ware example is more unusual but the moulding of the portrait is a little less well defined.
All three items are part of the Methodist Collection at Lincoln College, Oxford.
