Detonator Warning Sign.

I got this detonator warning sign years ago and just found it during a tidy up.
A colourful sign to educate children about handling dangerous items , but nice to add to a collection.
Measures 330mm x 208 x 2.5mm cardboard.
My question is which company or organisation would have made this item? Found at an Australian Gun Show.

I am surprised to see no comments about my sign.
The IAA Forum in USA liked it and member Fede identified the maker as Queensland Health Education Council. Thanks.

Which "Grown Up" should I tell immediately?
