Narrative:

Takeoff at V1 13L jfk, on rotation, a 'clunk' was heard. All engine instruments and flight instruments were normal. It was assumed that he had rolled over a runway centerline light, climb out was continued normally. Upon arrival is bos, a non-normal vibration was felt in aircraft at flight idle/ground idle. Post-flight inspection revealed damage to left propeller. Neither crew member saw anything abnormal on runway on takeoff roll. Subsequent investigation revealed an air carrier had blown a taxiway sign/marker out onto runway 13L and that is what caused the 'clunk' and propeller damage. Use caution and be alert for anything when operating around the 'heavies.'
