Bundesarchiv Material in Public Domain

[Adriano Baumgartner]

Hi!
I have just bought a Brazilian aviation magazine that ( it is not the first time that it occurs ) have used dozens of photographs previously published on Prien´s books, Bf 109 in Action book, etc...it seems mostly Bundesarchiv photos. Certainly they are not private ones.
Does the copyrights for magazines differs from those for books? How does it works?
Nice to see that in Poland, at least the prices are cheap than in Germany. I quite do agree with the last posting. The charges could be reduced a bit more to facilitate the full access for everybody.
