Mystery Shop - Tat's, Walteria

Has anyone ever heard of a shop once located in Walteria, CA. called "Tat's"? Perhaps from the 1950s or so...

I have a little ceramic 'weed pot' (which is a small vase with a tiny opening for just one small branch or flower).

The pot has a little round label on the bottom, which is somewhat worn, but readable. There is a small picture of a potted plant on the label, "Tat's", and "Walteria, CA", so I'm thinking "Tat's" was a gift store, a potters, or even a small nursery. Perhaps even an individual.

Any info is appreciated and welcomed.
