VERY FINE APPEARANCE. EASILY ONE OF THE FINEST RECORDED BLOCKS OF FOUR OF THE 4-CENT PAN-AMERICAN INVERT.
A review of our Levi records located seven blocks of four. Two of the blocks have perfs cutting into the design. One has not been seen since the 1944 Col. Edward H. R. Green auction and has probably been broken into singles, and another has not been seen since 1970. Of the other two well-centered blocks, one has a crease and thin spots, and the other has thins. This is one of the finest blocks of the 4c Invert in existence.
Ex Col. Edward H. R. Green, Y. Souren and Lilly. With 1968 P.F. certificate
