The Valdivieso advertising sign (Spanish: letrero publicitario de Valdivieso)[1] is a rooftop outdoor advertisement at 93 General Bustamante Street, Santiago, Chile.

Erected around 1954, it was declared a National Monument of Chile on May 31, 2010.

The Valdivieso advertising sign was built in 1955 by the Luminosos Parragué company.

[6] General manager Claudio Parragué stated:"The companies wanted their products to portray a sort of 'magic.'

That's why we used a mechanical electromagnetic system that, in time, ended up transforming the champagne bottle into a classic icon.
