The radios were made in art deco style
A collection of rare plastic radios from across the world, including globe, clock and dollhouse designs, are to be auctioned in London.
Made between 1930 and 1950, the 148 vintage radios are expected to fetch £80,000 when they go under the hammer at Bonhams in Knightsbridge.
A 1948 Emerson clock, boasting a blue and white marble effect case, is among the collection's highlights.
Experts said a Motorola 50XC model could fetch up to £6,000.
Jon Baddeley, Bonhams director of collectors' sales, said: "We are excited at the prospect of offering this important collection at auction and expect international interest not only from die-hard radio collectors but also from enthusiasts passionate about mid 20th Century design and early plastics."
The radios were made using Catalin, a type of resin allowing designers to create objects in the art deco style.
Production of Catalin declined in the post-war period as improved versions of modern plastics were developed.
The collection goes under the hammer as part of Bonhams Mechanical, Music and Scientific Instruments on April 28.
