I have the Panzers in Normandy and Battle of the Bulge ones at the moment and plan on getting the D-Day ones and The Market Garden one. They have some excellent photos, not just of tanks, and they have been meticulously researched so you know that the captions are accurate. They also show you what the areas in the pictures look like today.

They are a bit pricey, but worth it, the 2 D-Day books cover over 730 pages! The information in them is invaluable as well.
Cheers,
Rik
