Leda buttons were produced by General Plastics as a separate brand from around 1958, the name ‘Leda’ having been trademarked in September 1957. Advertising in 1958 referred to ‘Leda by Beauclaire’. Many of the buttons were simply re-issues of Beauclaire styles.
In 1963 F. W. Williams Holdings Ltd. bought a 50 percent share of Beutron Australia Ltd., and made an ultimately successful offer for General Plastics Ltd, which was described as being “integrated” with Beutron. Some Leda cards had the free cotton wrapped around the card, which was a G. Herring/Beutron design. General Plastics copied this from 1958, much to G.Herring’s dismay. They took the issue to court, but were unsuccessful in stopping it being copied. It must have been sweet revenge to takeover a firm that copied your registered design!
Entries from the 1960 Sydney ‘Pink Pages’ directory: General Plastics made the buttons, but Roger Berry distributed them.
Leda had various labels on the cards, including Boil Proof, Fashion Buttons, Permaloid, Permalon and Permalite. Whether this actually refers to varying plastics or not is anyone’s guess without chemical testing! Often the same button appeared with different names, as seen below, so I doubt there were real differences between the button types.
Leda-Beauclaire cards, 1957-58
The cards so marked possibly date before the examples simply marked “Leda”. There would have been a need to introduce the new brand to existing customers, before the name Beauclaire was dropped. Also, none of the ‘Leda-Beauclaire’ cards have the feature of added cotton which was introduced (copied from G. Herring) during 1958.
The card design was updated:
Boilproof
Many of the cards labeled ‘Boilproof’ and ‘Fashion Buttons’ are in poor condition. I think they were made by poor quality/brittle cardboard. The blue versions are a copy of G. Herring’s ‘boil-tested whites’ that were mounted on blue cards.
Fashion Buttons
Permalon
Matching buttons and buckles.
Permaloid
Permalite
Change of card graphics: Possibly early 1960s
Another change in card graphics c. 1965
The coloured background is textured to look like fabric.
1966-7: dual pricing
On these cards a change from cursive to block letters for the name ‘Leda’ is seen.
1967 onwards
The colour/texture is dropped, although the layout is the same.

Sample Cards: late 1950s-1960s
The Graphic design in the left top corner of the first 3 cards below appeared on some store cards marked Leda-Beauclaire, so date around 1958.
