MacMillan Pottery mark

Here is a huge tankard, with the wave pattern that MacMillan Potteries have become known for now, which was produced in many colourways. Shown next to a small swan to give an idea of size.

What is special about this piece, is that instead of the usual impressed stamp like the one in the gallery, this has a different big one, and, a mark! I have never seen this before, either on their pottery, or on the potters website or in the book.

So a close up, which is not quite defined with glaze in it, but nevertheless, the first time I have seen it!

Well done sunny
