Demetre and Check Buttons

These cards have unfortunately been trimmed, but the pink examples were branded “Delphi”, and the white, “Check”. I had spotted “Check” buttons previously, but there was no country of origin printed on the cards. From the example showing the same button on both a Delphi and Check card, I presume they were distributed in Australia.

The square buttons are textured around the edge; as this is barely obvious from the front, and might catch on the button holes, it seems a strange design.
