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”. In 1963 F. W. Williams Holdings Ltd. bought a 50 percent share of Beutron Australia Ltd., and made an offer for General Plastics, 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 marketing tool, further confirming the ownership of Beutron of General Plastics Ltd/Leda.

A box that can hold around 6 cards of buttons.
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:

Boilproof verses Fashion

Fashion verses Permaloid

Permalite verses Fashion
Boilproof

The blue card must be to reference Beutron’s “Boilproof Whites” which always appeared on blue cards.

A little curiosity
Sample Cards: late 1950s-1960s

The top 3 buckles were supplied with the board, but not attached with the original yarn. They still may have been Leda buckles, just not the original examples.

This design was sold on Beauclaire branded cards during the early 1950s.

The three buttons on the bottom left were supplied with the card and are a Leda design, but are not original to the card.

‘Pearlised’ plastic fish-eye buttons. Note the two pearl beads at the top right.
