We removed the decals with judicious use of a heat gun and razor blade.
The wind chime on the starboard mirror was a gift from some neighbors around the corner. A few months ago, their dog had escaped his back yard during a fairly tumultuous thunderstorm. He showed up on our doorstep, shaking and wet. While we called the phone number on his tag, "Checkers" (as it turns out) made himself at home on our sofa and snuggled up to whoever he could and went right to sleep. Anyway, short story long...his grateful parents came by after a few hours to pick him up, and returned later in the day with the wind chimne as a thank you gift.
