FINE-VERY FINE APPEARANCE. A SCARCE COMPLETE SET OF THE 1857-60 ISSUE WITH CROSS-STROKE CONTROL MARKS. HIGHLY SUITABLE FOR EXHIBITION.
The magenta lines were applied in pen and ink to all values of the 1857-60 Issue at the same time, apparently while the stamps were still in sheets. They are very scarce. One explanation for their existence is that they were created for salesmen's sample books.
VERY FINE APPEARANCE. AN EXTREMELY RARE TYPE OF SPECIMEN OVERPRINT ON THE 3-CENT 1857 ISSUE.
