Embassy; G. J. Coles brand
The same style buttons, however the first two date from c.1959 and are not on Beutron style cards. Therefore they were made by General Plastics. The third has the Beutron ‘free added cotton’, so were made by Beutron (Aust) Ltd. after the firms were merged.
These date after October 1967 when dual imperial/decimal pricing was no longer mandated.
The card on the left dates from 1954-7, the other post 1971.
