This wonderful old pottery mixing bowl is unmarked as to maker. Creamy ivory with pink and blue bands on raised vertical ribs. This 7" mix bowl has the usual bubble pops inside the bowl and base chips that were glazed over so common in these utility items. There are no chips or dings to rim but base has hairline that does not go through to inside of bowl. Can barely see impressed into bottom what appears to read USA and a three digit number.
