Recently found this while clearing out my Grandmothers house

I found this and honestly have no idea what it is and was wondering if anyone could shed some light?

It’s got a company name on the back reading “Stereosound Productions LTD, Brighouse York.”

I am most likely going to keep it as a decorative piece for my house when I move in around September time this year. If anyone has any knowledge on it, worth or history etc, it would be greatly appreciated.
