Abbey Road - released September 26, 1969 - back cover.
The blurry shadow to the right of "BEATLES" appears to be a skull with a crack and brick contour forming an "X" cross-bones. Together, they are the nearly universal symbol of death.
At the upper left, eight dots, resembling bullet holes, are inexplicably positioned on the wall immediately before "BEATLES". Connected, the holes form a "3" as in "3" Beatles. It is curious as to why the groups full name "THE BEATLES" was not used.
