The mural combines the Art Nouveau taste of Diamond with the theme of super heroes of Solo.

It is painted on the perimeter wall of Eni-Italgas, a historic company that manages the sale and distribution of gas in Italy, and behind it you can still see the "Gazometro", where in the past was produced gas from coal combustion.

The blue feline seen on the biceps of the heroine is Gaspardo, testimonial of Italgas for twenty years. Gaspardo was included in the opera as a tribute to Carlo Gaspardone, the famous publicist who created it in 1988.
