The US embassy had a pavilion there, too.
Over at Hall 1, Booth A38, is the Dar Al Kitab Al Arabi Publishing Company, which goes every year to the Book Fair.
Every year that company sells antisemitic books there.
Here is a large number of Mein Kampfs ("My Struggle"), with Hitler on the cover just in case you weren't sure what you were buying. (Mein Kampf was also featured in their front display.)
And here's The Protocols of the Elders of Zion, in the upper left corner of the Bestsellers section:
Detail from an advertising poster for this edition of the Protocols:
This antisemitic publisher was not in some small, dark corner in the back. No, these books were the first things one sees when entering the hall (at least one entrance).
This happens every year, and the US keeps going back.
