Reviewing this 10c MH plum I've had for awhile, and noticed a number of small marks, perhaps indicating a minor re-entry, or perhaps an inking issue. Most prominent in the N of CANADA, below the first A, and below the lower frameline, but also elsewhere. Didn't see a match on the re-entries site. Looking for input from the more knowledgeable as to whether that is what I'm looking at here.

Thanks! Greg
