VERY FINE APPEARANCE. THE 15-CENT E GRILL IS ONE OF THE RAREST GRILLED ISSUE BLOCKS. A BLOCK OF FOUR IS THE LARGEST RECORDED MULTIPLE FOR THIS ISSUE.
Our records contain only three or four other unused blocks of four, and no larger multiples. The Zoellner block of four was broken into singles after the sale, as have most multiples containing stamps with decent centering.
Ex Lilly. With 1968 P.F. certificate.
