Dutch, nice crack!
I like the large margin as well.
I didn't even look at the other margin, that how much I cared that it was off center.
This share isn't supposed to be a response to your crack, but I came here to share this one and saw your along the way.
#26 Pair - Positions 71-72L18 - on cover.
The BIG CRACK as seen on the left stamp is very collectible and sought after because of how absolutely bold it is. The second (right) position, 72L18, also shows the skinny end of the crack and while it is less sought after than position 71L18, it is equally as rare.
Having the pair still connected and on a cover is exactly what my collections would want to have.
And it does.
