How about a decade pin instead?
Art work and toys reflect era, while music is a compilation of artists?
I like the idea of same layout, different band. Would keep costs viable, sort of.
I still think a classic tv pin would sell, but I'm old, so there you have it.
Beastie Boys would be a hit I'm pretty certain.
I can't see single band pins worth the cost anymore, but of course, the bubble on pins is popping soon anyway
