enormous even margins all around, intense impressionEXTREMELY FINE GEM. THIS ORIGINAL-GUM EXAMPLE OF THE 2-CENT F GRILL -- WITH ITS PERFECT CENTERING, JUMBO MARGINS AND INTENSE IMPRESSION -- IS ARGUABLY THE FINEST IN EXISTENCE.
The margin width on all four sides of this stamp required all eight surrounding stamps in the sheet to be off center. Even in used condition, this Black Jack would be remarkable. In this original-gum state, it is an extreme rarity.
