Here is a substantial and iconic terling silver brooch by the Danish modernist master Poul Warmind (see maker bio). The spikes on the stylised hedgehog design are emphasised by the application of matt black enamelling.
This example was probably an official gift, maybe on a cruise ship, in 1969, as it is inscribed Threshold Class, 1969
