Misplaced Die Perf

I just came across this two days ago when going through a pile of stamps that were given to me by a friend.

Look carefully to see that the vertical die cut perfs are off by 50%. It first caught my attention when I noticed that the corner perfs were oddly shaped and then I saw the elongated diagonal cut that should be on the corners.
It is smack dab in the middle of the stamp.

Maybe this is fairly common, what do you think?

It is normal, it comes from the sideways oriented stamp.

You do have observant eyes!

Here is a pic, I have circled the die cut in question using a red circle.

Thanks Kim,

I may have observant eyes, but you've got the knowledge!

Your posted photo is the first time I've seen a booklet with one stamp oriented differently than the others. There is always something new for me on this forum.
