It's true... older graves may have tall headstones that are 'grandfathered in', but many (most) cemetaries will only allow new headstones to be flush with the ground. If there is a headstone there, it's a small one.
Another thing to consider, not knowing when the photo was taken, is that it sometimes takes a few ~months~ to have a headstone made and placed.
All this is just to help inform... not to explain this awful picture.
Exactly, and thanks.
