Vintage Fiesta Yellow Mixing Nesting Bowl #6 NO CHIPS CRACKS

This beauty has rings in the bottom. Circa 1934. Perfect shape. No damage what so ever. Many more listed in my shop. This is Number 6 in Yellow. There is a small glaze skip on bottom of rim like one inch. The rest of the spots are just reflection. You can’t see when nested at all. See pic 3. That’s the only flaw.
