This sterling silver Modernist pin was designed by Hermann Siersbol of Denmark.
The overlapping circles design measures 1 3/8" in diameter. The three circles are made of squared metal for a clean, mid-century take on the classic eternal circle of life motif.
A safety roller clasp secures the pin stem. On the back is stamped "HS Denmark" and "Sterling". The pin has good heft at almost 8 grams. Condition is very fine.
