Good question,I don’t know.
The original picture of 0 with the leis doesn’t have OBL in it; IIRC it’s from when he was in Hawaii.
In the other two pics, OBL’s head has been superimposed on someone else’s head; the angle is wrong- the heads are flat on the page.
Looking at the 0 picture again, the OBL head is flat on the page.
Photoshopped.
