I have tried but failed to find information on this artwork; without knowing more details, such as the name of the artist, it is really impossible, and there may be no information available anyway.
As it stands, the only way I can make sense of it is to assume that there are a series of logs made out of palm leaves (troncos de hojas de palma), and that these logs have been put together (ensamblados) to make a structure which, judging from the title, resembles or represents a whale. |
