By the end of the 60s, Mrs Herren taught cursive just like this leaked pic. Some letters connect on top, like a "w" or an "o", but most connect on the bottom. And the n had two humps (I'm not sure why, but probably to keep it from looking too much like an "r").
But the important thing is yes, that's a nice uniform. Same thing in gray on the road and we're done.
