Oh, patents! Hexogonal Altina Schinasi eyeglass frame design

Copyright © Françoise Herrmann

Altina Schinasi designed several other spectacle frames, beyond the enduring cat-eye spectacle frame. The below hexagonal Schinasi spectacle frame was granted a US design patent on August 4, 1942. The hexagonal Schinasi design also accessorized the traditionally round-spectacle frame design that dominated the optometric market of the first half of the 20^th century. 

The US design patent, USD133263, titled Pair of spectacles, was granted to Altina Sanders, also known by her maiden name, Altina Schinasi. Below, the patent Figure 1, showing a perspective view of the hexagonal Altina Schinasi spectacle frame design.
