Zauberkreuz bra

My first post will be about a bra which, in German, is called a Zauberkreuz, a magic cross. 

I got this vintage item in the original package. There is a text on the back of the package with a date so this is one of the view items that I can really date correctly. It was made in 1978. 

The size is a 70C.

I looked up the brand and they still sell their classic bra lines!
