Nazi county fair ribbon? Or what

[mwliles]

Greetings, I recently acquired this ribbon and was wondering what it represents? I think it is National Socialist Germany from the colors and it did not have anything attached inside the rosette. Many thanks in advance to all of those that take the time to reply.

I also thought it could be a ribbon that the new Soldier wore the day he showed up to be inducted?

And the last!

Seems to be some kind of Imperial Prussian regimental badge missing its center.
