1943 Campaign to
Increase Industrial Production - Plate Varieties and Errors
Plate Varieties
Helen Zirkle listed 18 consistent plate
varieties in her book which she numbered "a" to "r". Dr Y. Mishima
was able to study the plate used in the manufacture of this stamp
and has confirmed that all these defects appear. Many or these
varieties are very minor and hard to see. Having access to a complete sheet it is
now possible to confirm her work and to show pictures of each
variety listed in the order in which each stamp
appears on the sheet.

description better than stamp 45, as possible mistake?
