The cars and bicycles in this exhibition all have a connection to the Norwegian royal house. At the same time, they tell their own stories. They reflect the life of the royal house and changes in Norwegian society.

Crown Prince Olav's "Baby Cadillac" from 1912 was a toy car, but at the same time has a place in the early history of electric cars. King Haakon's stately Minerva from 1913, which he bought a few days after obtaining his driver's license, served until the 1930s. Before World War II, King Haakon also owned a Raleigh bicycle, which was among the most expensive bicycles you could buy. The open Buick carried Crown Prince Olav through Oslo's streets on 13 May 1945 and is a picture of the days of freedom after the Second World War.

The Norwegian Museum of Science and Technology has several "royal objects" in its collection. In the exhibition I/O (plan 4) you can also see King Olav's large mobile phone from the 1980s, in the exhibition Life and Death (plan 2) you will find electrical treatment devices provided by the Palace, while the music exhibition (plan 2) shows Queen Maud's gramophone and her self-playing piano from the early 20th century.

The open Buick, which brought Crown Prince Olav through the streets of Oslo on 13 May 1945, symbolizes the days of liberation after WW2.

The Norwegian Museum of Science and Technology has many “royal objects.” In the exhibition I/O (top floor) you can also see King Olav’s huge mobile phone from the 1980s, in the exhibition Life and Death (ground floor) you can find electrical treatment apparatus donated by the Royal Palace, while the Music Machines exhibition (ground floor) displays Queen Maud’s gramophone and her self-playing piano from the early 20^th Century.

At Christmas 1912, nine-year-old Crown Prince Olav was given an electrically powered miniature car by his grandmother, Queen Alexandra of England. The car was a children's version of a Cadillac Roadster, which was nicknamed "Baby Cadillac". It had a range of 25 kilometers and a top speed of 20 kilometers per hour. The crown prince drove around Bygdøy royal estate, even before his father had got his own car.

The English importer of Cadillac produced two such miniature cars for motor shows in London and Paris. The cars ran on batteries and were driven by an electric self-starter engine, which was a novelty Cadillac launched in 1912. A total of three cars were made, but Crown Prince Olav's "Baby Cadillac" is the only one we can confirm still exists. It was given to The Norwegian Museum of Science and Technology in 1948.
