German jewelers Schreiber & Hiller were in business from 1920-1993 in Pforzheim, a center for jewelry and watch-making for over 250 years. Many vintage costume jewelry collectors are familiar with their pieces from the 1930s (marked "DRGM 1138525", for their patent) and the 1950s (marked "ESHA" – which represents the German pronunciation of the first letters of their company name – and "RANDEL"). This collection of bracelets, brooches, earrings, and necklaces feature many variations of their tank-track theme as well as a delightful array of color and material combinations.
