The Paris Diplodocus in 1908, which hasn’t changed much since those days. The (second-floor) gallery with the cast is deserted, but look at the multitudes on the third floor. This leads me to suspect that it must be taken shortly after the mounting of the cast had been finished, perhaps even on the eve of the unveiling (June 15, 1908) by the French President, Edmond Fallières.
