Is This An Error

It appears that a bit of green ink is missing in the encircled
25 cents area of this 699:

no...flyspecking.

Upper right borderline, more flyspecking?

Thanks with appreciation for the replies.

stampfan9,

If you like your .25 stamp, and you enjoy the activity of flyspecking, I suggest you hang onto it and see if you can find others. If this mark is a result of damage to the plate (and not just an artifact of the inking process), and you can demonstrate it though a half dozen examples, you may find other collectors who appreciate it and, who knows, after a while you might get the catalog editor's attention (emphasis on "might").

Be sure and look for multiples with selvage or whole sheets to see if you can identify the plate position this guy occupies.

I am an inveterate flyspecker of U.S. stamped envelopes. I would certainly hang onto an envelope that had a mark of this nature.

Good luck. Be sure and update this thread if you find any others.

Thomas,

I'm curious, (I really am) for intaglio printing what kind of damage to the plate could result in a colorless printed area in the midst of a field of color like that? An uninked adhesion? Or were you referring to relief and transfer varieties as well with the expression, "damage to the plate"?

Is the situation different for the printing of embossed envelopes? (Here is where the curiosity is highest for me)

essayk, you are correct, the kind of damage I was envisioning for this stamp would work fine for LETTERPRESS, but for INTAGLIO it would be a whole 'nuther matter.

I spend a high percentage of my time with U.S. embossed envelopes (which used letterpress exclusively until the 1970's), and responded (too quickly) with a letterpress frame of mind.

Not being an intaglio person, I don't readily know how this artifact could be created. I will defer, at this point.

Sorry for the confusion I caused.
