RichardDavid,
I believe that a "power erase" is quite different than a regular erase.
I once had a card that had been "power erased" which basically was a 1957 Topps which was off-center. Apparently someone had used an eraser, or electrical power eraser, to actually wipe out about a 1/8" strip of the entire image to make the image appear more centered. The ink is gone and the white card stock underneath looks like it is part of the border.
