The Ericsson Dialog is one of Sweden’s most iconic telephone designs.
First released in 1964 by Ericsson, this sleek and stylish phone became a global favourite,
with millions sold and a strong presence in homes well into the 1990s.
Designed with both form and function in mind, the Dialog represented a shift in how telephones looked and felt.
Among the rarest variants is the 1971 Clear Ericsson Dialog,
a transparent field trial version used for internal testing and demonstration purposes.
These clear-cased phones were never released to the public, making them exceptionally rare and highly collectible today.
