More German adjective endings in English

In this post, I discussed whether to decline German adjectives when you use them in an English sentence. I don’t, but here’s somebody doing it on the Wikipedia page for Leo von König:

He was not well thought of by Adolf Hitler, however, and his works were removed from the “Großen Deutschen Kunstausstellung” at the Haus der Kunst in 1937.

Had I written that sentence, it would say: …his works were removed from the “Große Deutsche Kunstausstellung” at the Haus der Kunst in 1937.

So there!
