Interesting pair of shots.

In the album cover we see their whole bodies from feet to heads. Bob's head is about even with the top floor of the Sentinel Building -- Curt's head at the first or second floor.

The space between the trio and the building is flattened looks a lot less -- the building appears closer.

To accurately replicate the shot the photographer has to use a telephoto lens and stand some distance back and probably have to hold the camera near the ground.

Not to mention the need to knock the building down just above Curt's head.
