Great photos Funky!
The last photo would NOT be from the same moment in time due to a quite a few differences in the photos.
1) In first two pix Elvis sits in the driver seat while in the passenger seat in the last photo.
2) In first two pix Elvis wears his leather-bracelets (or whatever they are called) on both wrists while in the last photo he doesn't.
3) In the second photo the car is barely seen in the lower right corner and looks to be of a dark colour while in the last photo it seems that at least the body of the car is white.
4) In the second photo Elvis has no ring on his right little finger while he does in the last photo.
Anyway, great photos and most likely from around the same month of time.
