I believe these pics were taken late on the 22nd, just before Drain took the items off to Washington. They were taken by SA John Doyle Williams. They were released with the cover sheet description below but I can't find a reference to the hand drawn picture next to the rifle:
I'm sure that your correct, Dan.... Yo da man, Dan!! .
That photo has always intrigued me.... What was the purpose of the sketch of the man in the photo??
The photo had to have been taken AFTER Lee Oswald was in the custody of the DPD, so if that sketch was supposed to be of the owner of the rifle, it wouldn't have made sense to pose a sketch, because they could have used a photo of Lee and there would have been no need for a sketch... ( the sketch doesn't look like Lee Oswald anyway. ) Sooooo WHO is this guy??? As Michael said the sketch has a very strong resemblance to " the "Spanish boy " ( Cuban ?) .
The photo had to have been taken AFTER Lee Oswald was in the custody of the DPD,If the photo of the rifle was taken around the same time as the one of the shells it had to be taken some time between 10:00PM and 11:45PM on the night of the assassination.
Note in the pic of the shells - the two hulls are a darker colour than the live round. The darker colour is caused by the dusting powder Day used to look for prints but the live round is clean, even though Day testified to having used the black powder on this as well.
Oswald had been in custody for hours by this point and was already being viewed as the sole assassin of JFK so the "artist's sketch" is a mystery indeed. As I say, I can find no reference to it as part of the evidence being taken by the FBI but it is there in the photo, so what gives with that? It really is baffling.
