I don't collect Revenue stamps, but I would like to know if I should label it as hand stamped or a printed cancellation. It is clearly not pen and ink canceled and while it has some light smudges, I don't see evidence of it being handstamped. The front image shows the light partial imprint of an uninked cancelation die, while the back image, tilted to 30 or so degrees, shows two such uninked die impressions.
