This has been in my collection for some time and I have kept it as football memorabilia from the VFL, Victorian Football League days.
It’s a Clapper made by Champion, being wiggled in the hand it made a lot of noise like clapping.
I vaguely remember this style being available in the 70’s. Does anyone have any further info to refresh my memory, like was there different colours for different teams, and was there a time when they were popular?. Comment below thanks!
