Valve Ephemera: Ediswan Advertisements

April 1950 - Look Behind

Invites you to look behind the screen (like the old and young peeping at a football match) to see how many use Ediswan valves.  "..and there's a very good reason for that ... but we're too modest to mention it.
February 1959 - European Type

Focus on replacement for European types by taking the advice of your Ediswan Mazda Rep. "... make a friend of your ... Rep."

"There's something behind it all!", "Look behind the screens". "... and don't forget to order your supplies of 'Siemax' and 'Full o' Power" Batteries' "
