A mystery company; it was possibly located in Melbourne in the 1940s, but I have not been able to confirm this.

The only products I have seen so far are cruets (salt/pepper on a stand), in green/maroon and black, blue, and red, and this butter dish. The distinctive design of the salt/pepper are seen with branding from other makers. Either Ibis supplied the other firms as well, or they were making the design under licence.
