On the real stamp and the proof, what's up with that vertical line along the right side of the stamp image?
Thanks, Robert
Robert,
I have wondered about this very thing in the past, but you have sparked my interest.
I checked the only reference book I have available to me, the "US Postage Stamps of 1869", by Jon Rose, and can find no mention of the vertical lines on the 90c Lincoln stamps. Not being familiar with the way these were printed, I can only speculate based on what I have observed.
I have observed the following:
1) Looking through all of the pictures in the book, every postage stamp, proof, and essay has these vertical lines that extend above and below the stamp along the right frameline - including the famous unused #132 block of 12. There was one exception - the large and small die proofs.
2) The vertical lines are printed in the same color of the frame of the stamp
3) The vertical lines do NOT consistently align themselves to the right frameline of the stamp. That is, the vertical line can intersect or miss the stamp altogether.
I like to speculate, and this is no exception.
If I were to take a stab at this, I would guess the following -
The plates consisted of 100 dies. Because of the inconsistency of the location of the vertical lines, I would guess that the line did not originate from the dies or plates themselves, but from something on the printing press. The ONLY reason I think this, is that the vertical lines vary in location - either missing, or intersecting the design of the stamp - something that would not be possible if from a die or plate design.
Again, this is just a guess. What it actually is from is gunna keep me awake. Perhaps one of our experts can point me to a better book on 1869s?
