The date in the top right corner looks like March 1912. If that's the case this photo could be part of the build up for the Fireman Jim Flynn fight that took place in Las Vegas that summer. Johnson won that fight and again defended his hard won heavy weight title. However, it was the last time he defended the title in the USA, fighting (and winning) twice in France before losing the crown to Jess Willard in Cuba in 1915. This photo could also be considered a mark of the end of Johnson's glory years. After the Flynn fight he would be forced to move abroad to aviod arrest for various claimed crimes and wouldn't return to the US for 7 years. His next fight in the US was in prison.

This is one of 4 Bain Collection photos of Jack Johnson taken in the same place and apparently at the same time. This one is dated May 3, 1912

Named after French naval architect Stanislas Charles Henri Dupuy de Lôme (15 October 1816 – 1 February 1885). Not sure if it's this one or a later airship named in honor of Dupuy de Lôme: "The Dupuy de Lôme airship was 36 meters in length, 14.84 meters in diameter, 29 meters wide, and had a total volume of 3,454 cubic meters. It was powered by a 2 horsepower (1.5 kW) engine, providing a speed of between 9 to 11 km/h. The basket under the balloon could carry eight, several operating the balloon and others observing. She was the first operational airship, and was employed during the last days of the Franco-Prussian war."

Rosenborg Castle was built as a royal summer residence by King Christian IV in 1606-34. The King designed the Castle himself in Dutch Renaissance style and lived here until he died in 1648.
