1-3/8" exceedingly rare litho button by Greenduck, Chicago. Front features crudely drawn skull and crossbones pirate symbol also featuring lettering as if hand drawn "Watch Out/Coming/Coming/Sea Hawk." This classic movie was directed by Michael Curtiz and with Flynn were the stars Brenda Marshall and Claude Rains. Trivial trace of paint wear in the form of a couple tiny white dots but very minor. Button is Exc. and the only example we've seen in five decades.
