Also, if this was only delivered to parents in the context of that particular school (e.g. given out at an event at the school, or given to the children to pass on to parents) then it might not be necessary. A little bit of context goes a long way, as we well know in these forums! However, I would be surprised if the school is not mentioned somewhere on the flyer.
I am embarrassed now. Yes, the flyer does indicate the name of the school in smaller size at the top of the handout. I just wish the school name is a part of the announcement title. Anyway, thank you both Panjadrum and MM for making sure that I note the detail. I think the announcement is printed on the school letterhead.
