Looking through the April 8, 1939 issue of Business Week, I see on p.49 a picture of Germany's "new official, colonial map" entitled "Germany's Latin American 'Aspirations'". Could this be what your professor is looking for? The caption discusses German colonies.

Subject: [SERIALST] Mystery citation-Business Week?
I've been asked to track down a mystery citation for a faculty member.
This is all the information we have:
Date: April 8, 1939
Journal Title: 'United States Business Week' (note: the professor
received this information from a source outside the US.)
The article is about colonies of Nazi Germany.
We've checked Reader's Guide Retro, WorldCat, and Business Week without
success. If anyone has any ideas, please reply directly to me. Thanks
