That poster is a FAKE.
That would be my conclusion based on a number of observations.
1. It is made up of pieces of well known historical posters, particularly one of a HJ (hitler Youth) congress.
2. The s used in black-letter (Fraktur) which looks something like an f (without the little cross-piece) is not used at the end of a word like "Nazis." At the end of a word, one uses the more normal-looking s. One th poster, they did not get it right. On this poster the makers used the f-like s at the end of the word Nazis, showing that they did not know exactly what they were doing.
3. The world Allianz (from French) is understandable in German, but would not be the normal or preferred German word. They would be more likely to sue Bund.
4. The German word Treffen means more a meeting, like a meeting of two people in the street. It would not be for something like an assembly, which would be a Versammlung or Kongress.
5. It would be shocking for a true Nazi to show the German man shorter than the Asiatic.
6. Although Geobbels himself used the word Nazi, it was not the preferred word in propaganda, including posters. There one would refer to National Socialists or use the abbreviation NS.
My guess is that this poster was made by some neo-Nazis who didn't really know what they were doing, or even as "black propaganda" by Israelis making the point of the similarity of some of the streams of hatred in anti-Jewish hatreds. It is also possible that some Palestinian group made this thinking to enlist support from neo-Nazis.
Great exegesis.
-- I noticed the last "s" but i was not thinking about the different way of writing it.
-- A possible explanation for the poster could be, that it was a reaction to this 2004 event, which was cancelled:
The goals of the previously planed Arab & Islamic congress in Europe were the solidarity with the Palestinian and Iraqi people suffering under occupation, to make distinction between terror and legitimate resistance against occupation, to avert discrimination against Arabs and Muslims in Europe and to unify and build a federal union for the Arab and Islamic unions and Institutions as well as to give the right and true picture of Islam, the last mission and seal of the revelation religion.
Through a letter of the "Simon-Wiesenthal-Center" in Paris to the German interior minister Mr. Schilly accusing the Congress of being as "Jihadist" and as a market for „radical jihad“ there has been a groundless turbulence in the German policy n within the local and international Media.
The German security officials had already declared that they are observing the preparations since May 2004, i.e. since 4 months. They have been studying it. There are no reason to forbid the congress unless there are a crime.
There were indeed an unusual style in the Arabic and English text set by “Humanity On Hold”, which represented only one element and not the whole participants at the planned congress.
The coordinator for communication Mr. Gabriel Daher denied during the last time all accusations raised against the planned congress.
Under false and bad mass media and under strained political atmosphere it was contradictory to the aims of the planned congress to continue and get the resident Arabs and Muslims in confrontation with the mass media and with the already fixed political positions.
This website will be maintained not as a political platform. It will be used for intellectual and religious discussions and thoughts.

I wouldn't call it a FAKE because I don't think that anyone has claimed it is a real poster. It looks like a Photoshop spoof, not a very good one considering the perspective of the figures.
