This diminutive pin is the greatest! Made in the 1960s, it depicts a mop-headed quartet of singers . . . most likely the Beatles. The four guys are even wearing Edwardian suits, like the Beatles did when they performed on the Ed Sullivan show. Goldtone cast construction, with red and black enameling; rollover clasp pinback. Marked "NEMO c". Condition: excellent. The heads are not entirely enameled, but it appears that this was deliberate. This is a TINY pin, only 1.25" across.
NEMO was one of the marks of Brier Manufacturing Co., Providence, RI, which was in business from 1913 to 1978.
