Two new Embassy cards dating ?late 1970s or 1980s. I have not seen the the airplane design previously. See http://www.austbuttonhistory.com/australian-button-history/g-j-coles-embassy-brand-1929-1994/?preview_id=642&preview_nonce=3620594008&_thumbnail_id=-1&preview=true#Transfer_printing_on_water-white_cellulose_actetate for similar style buttons.
The design of animal buttons below date from around 1954, when general plastics sold them as ‘Tiny Tots’ buttons. These are later variations.
However, the Goofy buttons above were originally one of four Disney designs that dated from 1948-1953. http://www.austbuttonhistory.com/australian-button-history/disney-buttons/?preview_id=927&preview_nonce=ba624ad061&_thumbnail_id=-1&preview=true#1948-1953
It is possible the Disney buttons were supplied to Coronet/Rex C. Norris by General Plastics (or its predecessor). It is also possible that Rex C. Norris was the first Australian firm to produce them.
