I dont' see the exif info, perhaps I am downloading the processed picture...but if these shots were made any where close to wide open, DOF is bound to be razor thin.
Some of this could even be due to positioning or angling of the camera or the shot by just an inch if they were made at close quaters (looking at the pictures, clearly these were very close shots)...in this case a slight tilt in the camera will render one or the other edge/border of the printed page out of sharp focus depending on where the focus point is.
His 5D2 has no leveling feature unlike 5D3...and even then...unless these shots are made very carefully under controlled conditions on tripods and with leveling, pixel peeping is rather fruitless at such close quaters on a tele lens wide open.
