Definitely the widest example I've seen of this stamp, with three large margins. Sound, uncut, and with just faint evidence of a blue handstamp cancel at center. Unfortunately (or fortunately, depending on how you perceive the practice) the top-to-bottom centering precludes any numeric grading.
Regardless, you likely won't ever encounter a jumbo of this stamp with margins this wide. There must have been some fairly narrow stamps elsewhere on this sheet.
