Gustave Eiffel and portrayals of great humans

Under the northwest leg of the Eiffel Tower tower is a bust of engineer Gustave Eiffel. Portraits of outstanding individuals are usually not made until they are old or even from memory after they are dead.

As a result, those of us in later generations have a harder time grasping how those individuals were in their prime — vigorous, purposeful, and vital.

Is this Leonardo da Vinci? Is this Andrew Carnegie?

So I like very much this eternally youthful bust of Eiffel.
