To preserve it, place it in an acid free page protector and keep it in a safe place. Scan it into your computer so the dat is saved incase something does happen to the original. Print out a couple copies to refer to so you do not have to handle the original too much also.
Did you find it in the back seat? If so, be sure to look inside the front seat backs as well, you may find one or two more sheets.
Off the top of my head, I remember one panther pink Challenger SE and it had a Gator top, there is a pink R/T SE in Canada as well. I will check my files and see if I can spot any others.
