Thx Ross, I have a couple in light blue throughout, it does look quite a lot like a Per Lutken colourway. The only alternative pattern this vase could be is a Jan beranek design from the same time, but this would require three blobs sticking out of the vase near the base, which I cannot see from the picture. If these are not present, the shape and height makes a solid attribution for the Emanuel design previously mentioned, as suggested by Langhaugh too, it was made in two heights 22cm and 16cm, a nice piece,
