GLADSTONE'S cheeky preps showed their true colours when they met The Observer's photographers earlier this year.

Before you grab your copy of today's Observer prep feature, take a look at some of the funny (and impressive) faces Gladstone's preppies make.

It's also worth noting the fabulous looking teachers who don't mind going cross-eyed for the camera. 

And parents, if you spot your child and you're a little concerned, don't fret - the prep feature will be filled with different photos of your youngster's smiling faces.
