I have a number of these stamps in an array of various colors in the blue and green and blue green hues, but never have I seen a copy as "rough" as this...and on a Cincinnati Bureau precancel, too.

The image appears blurred. The fine line engraved details of the stamp appear all but lost (because of over-inking?)
It looks as if it could almost be that there was too much moisture content in the paper when the stamp was printed.
Is this a common occurrence?
