mid century mod vintage USA ceramic bowls, fall leaves w/ haunted tree Brock California pottery

I love the autumn tree design on these mid century vintage ceramic bowls. These have no makers marks though they're USA made - these look like Brock pottery to me, just the general style and colors of the design, and the weight and feel.

They're 5 1/4" in diameter, fruit or dessert bowls. They'd be good for candy, olives, all sorts of tidbits. This is a set of four bowls, all in very nice condition without damage or wear.
