Good Evening,
I believe there is a re-entry of the entire stamp on this stamp - but it's going to take some work. I'm hoping essay_proof can jump in to assist. To me it appears that it's easier to see - NOT ZOOMED IN. It's a light green impression that covers the left side of the stamp from top to bottom. I have various sizes of images below to hopefully let you see what I see... I swear I can make out a "5" near the bottom left...
Yeah, it looks dirty - but that's what lightly re-entered green would look like.
This one needs ***investigation*** - Let me know if you'd like any other sizes.
Please stay on topic - much appreciated.
