The booklet was folded too soon after printing causing tagging offsets for both the general tagging and the footprints.
The result is 4 stamps have double sets of footprints, one set lighter, and the middle pane has an offset of the general tagging plus the footprints.
The pictures represent the stamps in this lot, I was fortunate to acquire a few examples, the pictures are of one of the booklets, all of the booklets have this same error.
