Roberto Burle Marx’s only US example

In response to a NY Times article about Marx:

In the mid 50s our office designed a large residence in Havana. Through dad’s contacts, we somehow attracted Marx to offer a landscape design for that project.

In 1955, we were working on the LA Headquarters building for the Amalgamated Clothing Workers Union. Dad convinced Marx that this would be a great opportunity for him to show his mural talents for LA. We have a picture of Marx putting the finishing touches on that piece;. the only live example of this man’s work in the US! It would appear that the paint was applied directly to the plastered surface, as opposed to a canvas being adhered.

Amalgamated Clothing Workers of America - Roberto Burle Marx

We have tried repeatedly to make contact with the current owner, who has avoided us; who knows why, but we suspect he does not want to know about this treasure in his midst for fear of the responsibility this might reveal. We’ve reported this to the Mural Program of the City, but no one seems to have an idea how and under what authority something might be done here.

First, of course, it would seem, an experienced archeologist should scrape the white painted surface to see if signs can be found of this art work underneath. But what if it’s true; what to do next? It is not practical to remove this wall with the plastered surface intact, I would say, altho with enough funding anything is possible. But what to do with it if and when? I don’t think this owner would want to be bothered, even if funding were found for a restoration.
