CASUAL DRESS DAY AT NSC
1973

This is a photo that appeared in the Geelong Addy of a casual dress day where the teachers dressed in uniform and some of the kids dressed up as teachers. 

Couple of notes from the picture:

Students used to think that teachers dressed in academic robes and they hadn't even seen the Harry Potter films yet.

We are pretty sure that the metre long wooden ruler is still in the school somewhere!
