This listing is for a pair of metal vintage style CHROME musical note speaker grill covers that were a very popular add-on accessory back in the 50's, 60's and 70's. These were commonly used on the rear window package tray to cover 6x9 speakers, but they can also be used to cover 5x7 inch speakers and up to 6" round speakers. I have also seen these used on door panels. These do come mounting hardware. Buying a quantity of one with get you a pair(2) of chrome speaker covers.
