Chinese bowl

This is a Chinese bowl that Mom has had ever since I can remember. It sat on the chest of drawers in the living room. She says there is a larger twin at Salisbery House in Des Moines, Iowa. Her aunt, who raised her after her mother died, was the private secretary for Mr. Weeks. He was head of the Armand company (think cosmetics). He was an avid collector, so I'm guessing it came from him, to Auntie, and then to Mom. I always liked it because there are openings between the color bars so it has a lattice-like appearance. How did they do that? I grew up with color and art, without ever thinking it was unusual. Mom is a unique person. I think we all are a little bit like her...quietly quirky in a good way.
