3¢ Brown 34UR70
We are not certain that this is the proper image for this position.
"The vertical line of the right numeral box, the ends of the horizontal lines in the lower right and the upper right and lower right frame junction lines were doubled, and the right side of the frame was thick."
Research notes:
As Leo Beaudet suggests, the upper left vertical line is clearly retouched. Marler may have 'missed' this, or this image may not be correct for this position.
