I just found this site. Quite the collection they have of old school kits.
Holland • Classic Football Shirts
There are other countries. Kinda interesting to see the styles change over the years.

These are worse I think...

The idea is cool for that Holland jersey, but badly executed.
As for the green Germany jersey, there was a reason why it was green. If I remember correctly, Ireland were the first country from the allies to have an international friendly against Germany after WW2. The green jersey was created out of respect to Ireland for doing so. That's the apparent story to it.
Doesn't change the fact it looked like diherrea. lol
It fits nicely with other jersey colour choice legends like Boca Juniors and others.
