This is, of course, the crucial question in attributing any kind of artwork to a specific artist or atelier. So by way of example, I've pulled some signed Lao Tian Li pieces from my picture files that feature similar compositions and floral designs:
|Note the peculiar bracket-shaped veins in the leaves, and the spiky symmetrical chrysanthemum petals.|
|The next picture shows the full view of this vase.|
|This vase was the topic of a discussion at the Asian Arts Forum.|
UPDATE: A somewhat similar pattern in a vase pair displayed on a Chinese website. The signature stamp seems to be similar to that used on the lotus pond vase featured in a previous post, perhaps used in the 1920s or later.
