63TC5g 1c Dark Brown Trial Color Proof on Macdonough Patent Paper Block of 4

$120.00

Patent No. 52,869 was granted to James MacDonough on February 27, 1866. James Macdonough’s patent called for printing the stamps with a glycerin-based ink that would prove highly soluble in water. Once again any attempt to wash the stamp to remove the cancel would result not only in the disappearance of the cancel but the stamp design as well. The muddy brown ink (the only color used) used to produce this patent produces an image that is very sharp.
