We celebrated 50 years 9 years ago and did “MSB” on our oval. Advanced Life came in, did the calculations, marked it up and worked out how many girls to put in each letter. They had a cherry picker to take the photo which I had to hire.
We had seniors as the outline of the MSB and juniors within this outline [both wear different summer uniforms]. Staff were lined up at the back in a straight line.
Hope this helps.
