A very difficult person to find visual reference on- Also known as
Inga "Fejos", wife of Hungarian Film director Paul Fejos. Appeared in
two Danish films- "Storm Varsel" and the Paul Fejos directed-
"Millions in Flight" (U.S release title). Rumoured to be a one time
winner of "Miss Denmark" (year unknown).
Was investigated by the FBI under suspicion of Nazi spying inside the
U.S. Had an romantic relationship (1941-1942) with future U.S
President John F. Kennedy . Was photographed at the Berlin Olympics
with Adolf Hitler.
Any photographs of Inga Arvard would be ideal, although photographs
Taken with Hitler or Kennedy would be preferred.
Direction to retailed DVD or VHS copies of "Millions in Flight" would suffice.

Dear bensy,

This search indeed proved to be hard. The final result of my efforts
is not spectacular, but at least I managed to locate a portrait of
Inga Arvad, though alas without Adolf Hitler.

Inga Arvad's photo is part of an online article of the Swedish
newspaper "Aftonbladet". The article is about the women connected with
the Kennedy family, and Inga Arvad is mentioned as "...the Danish
beauty queen..." who had an affair with John F. Kennedy.

Here is a direct link to the image as included in that article:

And here is the full Aftonbladet article "Kennedy älskade makt och kvinnor" itself:

In case you need a better and larger reproduction of that photo or
contact information for the agency owning the rights in that
particular image, you might want to contact the Swedish newspaper:
