MC5 proves buttons and t-shirts are not mutually exclusive.

Pin out the jams, brothers and sisters.  Record covers feature special appearances by buttons.  A personal favorite is the insert for Kick Out Jams by the MC5.

How did they button their bare chests?  And more importantly, where can an authentic White Panther button from Detroit circa 1969 be obtained?

Post-edit:  Original MC5 White Panthers button revealed  here.
