|(or tubes if you are American) have recently been an area
of interest to me. The period this site spans is from the 1930's to the 1960's; a huge range of design styles and printing capabilities are encompassed
in the examination of such simple artefacts. By their very nature, the
valve boxes, advertisements and catalogues were disposable, making them fleeting ephemera of
days gone by. I have grouped the material by brand rather than company
as over the years many of the brands were bought by each other.
