NOS / New Old Stock chrome bumper extension or cheek bumper pair.  I believe these are correct for 1957 Chrysler New Yorker, Windsor and Saratoga.  They measure about 10-1/2" long at the top and 6-3/8" wide or tall.  The condition ranges from good to very good.  The right one is pretty nice with minor scratches.  The left is what I would call good driver quality ....There is some minor pitting.  Nice addition to any car.
