Frank:
I believe the heart stone and the H/P stone at the museum are the originals, with the two trail stones being copies.
If Travis found the heart stone in two pieces, as he told one of his friends, then Travis would have been the one who glued the pieces back together sometime after finding them underneath the 2 stones. For the bumper photo, the two pieces would have been held together by the pocket itself.
Bill:
If you look closely at the original ( the one with the fancy border) photo, there is virtually NO distortion of the grill lines, headlight or hood ornament.
Aside from the cracks, caused by someone folding the original print at some point, possibly by carrying it around in their pants pocket or pack, and some very fine wrinkling also visible on the left front fender (but not on the hood or right fender etc.) there is no other distortion. IMHO, they are the original stones.
As I said yesterday, I also believe the photo was taken at the side of the road, on the shoulder of US 60 opposite from where Travis said he found the stones.
The unlatched hood, as deducer has said, fits the overheating scenario, while the shadows of the bumper-bracket and stones indicate the sun was directly out front of the car...(late morning if the car was parked on US 60 and facing SE), and the blacked out portion indicates Travis did not want anyone seeing the photo ( locals mainly ) to be able to identify what was in the background.....Superstition mountain, the road cut, and the bridge.
