General Plastics (Leda)
Leda buttons were produced by General Plastics as a separate brand from around 1958. Advertising in 1958 referred to “Leda by Beauclaire”. However, In September 1957 the name ‘Leda’ was trademarked by Beutron, so the companies must have been merging, or General Plastics run as a subsidiary from that year. Some Leda cards had the free cotton wrapped around the card, which was a G. Herring/Beutron marketing tool, further confirming the ownership of Beutron of GP/Leda.
In 1963 F. W. Williams Holdings Ltd. bought a 50 percent share of Beutron Australia Ltd., and made an offer for General Plastics.
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:
Leda-Beauclaire cards, c.1958
Change of graphics: Possibly early 1960s
A little curiosity
The above are possibly late 1950-early 1960s.
