Nice bowl. I don’t recall seeing any like that.
A “pressed” ceramic bowl with a raised (relief) pattern on the inside with a mini-scalloped ?? rim.
Pattern and Carnival glass bowls, plates, etc. pretty much all have a raised (relief) pattern on the inside, …. whereas ceramic bowls are normally plain, painted or stenciled.
But for all I know at present, the bowl in question might be a “brown glass “pressed” bowl”.
