Recently I acquired a second hand book, The Home of Today. There's no date of publication but my guess is it's probably just after WW2.
However, the index shows rubber - pages 193 - l95, 'Rubber in the home'. At the subheading of 'bedroom' (mmmmm!) is the stirring paragraph:
"The great variety of rubber clothing now obtainable should perhaps find mention here. Apart from, raincoats and mackintoshes- which thanks to rubber are are no longer the dull shapeless garments of a generation ago, but may now be obtained in any design and in all the colours of the rainbow - even hats, umbrellas, galoshes and wellingtons may now be obtained in sheet rubber to match the raincoat itself. Rubber aprons and overalls are indispensable to the busy housewife, and are also economical, as they are merely sponged over when soiled."
