Hello pets3 and thank you for your question.
The model of car was an Austrian built 'Graf Und Stift'
"Ferdinand's Graf Und Stift
Three brothers, Carl, Heinrich, and Franz Graf, formed a partnership
with Josef Hans Stift to produce Austria's first automobile in 1897.
It was a brand-new, large Graf Und Stift phaeton, with a four-cylinder
engine and the first front-wheel drive-and Austria's heir to the
throne, Archduke Franz Ferdinand, rode in it during a visit to
Sarajevo, Bosnia. While in this car, Ferdinand was assassinated W.W.I.
In the next dozen years, this same car was owned by 15 private
parties, and was involved in six major accidents that cost the lives
of 13 people. After its last crack-up, in Romania in 1926, the Graf
Und Stift was retired to Vienna's Museum of War History, where it may
still be seen."
"In 1914, the sleek Graf und Stift automobile had a rendezvous with
history that changed the course of civilization. Built by the Graf and
Stift company -- which had its origins with the Graf brothers thriving
bicycle business -- the car was one of the luxury automobiles the
company built for a prestigious clientele. Among the famous people who
sought after the Graf und Stift cars were members of the Austrian
Imperial Court. Sadly, in 1914, the heir to the Austro-Hungarian
throne, Archduke Franz Ferdinand and his wife were assassinated by
Serbian nationalists as they rode in their Graf und Stift automobile
