Vintage Chinese Blue White Prunes Cherry Blossom 6" Ginger Jar Double Ring Mark

Description

This jar is very old and I can at least remember my grandmother having it in the 1960's, so she must have purchased before then.  It is 6 inches tall and has the original cork cover that fits under lid.
There are some anomalies that occurred during production.
The lid has some air bubbles and a crease (see photo).
There is a small indentation on the side (did not photograph well).
Rim looks like it has a crack but I think it is a stain, as it does not go all the way through to the other side (see photos).
