This is the Auditorio Nelly Goitiño in Avenida 18 de Julio, Montevideo. It appears to be oe of a number of auditorium run by Sodre - Servicio Oficial de Difusión Radio Eléctrica which means something like the Official Service for Broadcasting Radio. At least that's what I've come to understand by applying my very limited knowledge of Spanish to the Sodre website.
A frieze on the façade of the building represents the arts in classical form. The masks of comedy and tragedy are depicted in the frieze and separately on the façade.
MELBOURNE ART DECO
In 2009 Robin Grow published a book on Melbourne Art Deco, with images largely supplied by David Thompson. The book quickly sold out and he is pleased to say that it has now been re-published by Brolga Press, with updates, errors corrected and a new cover.
Best of all, it is selling for about $25 in the shops and on-line. Art Deco & Modernism Society members can purchase a copy from me for $22, (includes postage within Australia). For overseas orders please email for postage rates. Contact me at firstname.lastname@example.org if you are interested, and advise if you would like the book to be dedicated and/or signed.
