The image in question comes from a 1966 Baden-Württemberg conference convened by the Bundesvereinigung der Deutschen Arbeitgeberverbände (Federation of German Employers/BdA). The BdA is one of the major pressure groups of German industry and business and concerns itself with matters of social policy and labor laws. This particular conference had to do with the growing concern in the FRG with the growing number of foreign workers in the FRG labor system. As the Wirtschaftswunder solidified into West German prosperity in the 1950s, the FRG experienced a labor crunch in sectors like agriculture, mining, and other less than prestigious occupations. Initially, the FRG could rely upon refugee Germans from the GDR to fill these niches, but the erection of the Berlin Wall and the tightening of the inter-German border precluded this option. Bilateral agreements with Italy in the 1950s helped to set a pattern for foreign workers in the FRG which later opened up agreements with Spain, Greece, and Turkey. The influx of the latter category was a cause of concern inside the FRG as these non-German laborers sometimes flaunted their residency restrictions and other agreements made with the Turkey. However, the underlying cause of this tensions was that the FRG workforce was becoming less ethnically homogeneous and a permanent non-German presence in Germany's cities was becoming an unavoidable reality.

Both Bonn and FRG industry predicated the foreign workers as a temporary expedient, but such assurances could not erase the structural realities that FRG industry had come to rely upon this source of cheap labor in unskilled and semi-skilled sectors of the economy. The term Gastarbeiter itself, which increasingly began to be used by employers in the 1960s, implies such laborers were an ephemeral phenomenon. Despite the fact that foreign workers were paid less and subject to various restrictions on promotion, there was a persistent concern in both the FRG media and politics that foreign workers created a zero-sum game in the economy in which a foreign worker took the job of a German. The 1966 BdA conference was subject to a great deal of scrutiny in the FRG press. One of the stereotypes of these foreign workers worked harder for less wages, which played on long-standing German stereotypes about the value of German craftsmanship vis-a-vis cruder mass production, and one report from the BdA conference sought to dispel this stereotype. The BdA report that foreign work habits were not too dissimilar from Germans' sparked a degree of outrage in tabloids like Bild-Zeitung and token protest strikes in Baden-Württemberg. The BdA's support for Gastarbeiter labor came at a downturn in the FRG economy in 1966-7 and the support for this form of non-German labor was emerging as one of the perennial political hot potatoes in FRG politics.

As for the map, this is a cartographic visualization of the sometimes contradictory politics of FRG in the 1950s and 60s. You will note that the 1933 borders of Germany are present and the map does not lower itself to name the GDR as a separate state. On the surface, this might look like German revanchism, but it instead demonstrates a political position that the final borders of postwar Germany could only be settled by a proper peace treaty between the four Allied powers and a true German government. The division of Germany thus was a temporary affair, and for the FRG political establishment, the GDR was not a true sovereign state, but rather a non-sovereign entity. Most FRG politicians accepted the finality of the Oder-Neisse line and the loss of East Prussia, but kept this point alive because it both strengthened the legitimacy of the government in Bonn as well as a sop to the German expellee associations who were a strong anti-communist power bloc in the early decades of the Federal Republic. Brandt's Ostpolitik of the 1970s considerably softened this line, but some conservative FRG press outlets refused to even mention the name "German Democratic Republic" through the 1980s.

As for the use of England, this is an older naming process, many older German maps use "England", that would be akin to referring the Soviet Union as "Russia" or "Soviet Russia." It is technically incorrect, but represented older terminologies that were quite entrenched.
