Comparison of Types III and IV of the 2¢ Triangle: Line in
Acanthus
Crispness of the Line of Shading Inside the Left
Acanthus
Type III
Type IV
The
line of shading in the left acanthus is often well-defined
in the Type III stamp.
The
line of shading in the left acanthus is never fully defined
in the Type IV stamp.
Poorly inked Type IIIs will not show
the well-defined line of shading and exceptionally sharp Type IV stamps may
show parts of the line, but never as much as in the Type III example given
above.
All the Type III examples are from the same scanned
stamp, plate number 146, and all the Type IV examples are from the same
scanned stamp, plate number 762.
