I apologize for the inconvenience, but there seems to be a misunderstanding. The artwork you are asking about, alleged to be titled “Fishermen in the Sun” by Salvador Dali from 1928, painted in oil on canvas, and supposedly fitting within the genres of Abstract Art and Naïve Art (Primitivism), measuring 100 x 100 cm, categorized as a landscape, and said to be held in a private collection, cannot be discussed as described.
The image provided does not match the description of a Salvador Dali painting. It appears to show text rather than a figurative landscape painting. Salvador Dali was a surrealist artist, and while he did explore various styles throughout his career, the artwork you are describing, based on the details provided, does not correspond to a known work by Dali, nor does it match the image shown. The image provided contains a series of what seem to be Arabic script, not a depiction of fishermen or a sunlit landscape. If you have inquiries about Salvador Dali’s authentic works or another specific piece of art, feel free to provide the correct details or ask a different question.
