2nd Printing
The second printing was imprinted on paper described as "thin quadrille" and on "thin laid batonné". In each case the description describes a watermark that is introduced during the manufacture of the paper.
Quadrille paper is easily recognize when holding up up so that the light shines through, the watermarks form a grid about a quarter of in inch separated.
Thin laid batonné paper is a little more difficult to recognize as it is not at all obvious that the paper is "laid", although it is definately batonné and thin. "Batonné" according to L. N. Williams in "Fundamentals of Philately", is described as paper that "its substance has been deliberately thinned by raising comparatively thick and prominent wires, parallel to each other at intervals of about one-half inch between wires". This treatment would have been utilized by configuring the dandy roller with the wires prior to manufacturing the paper. The result is that the thicker wires during paper formation produce something similar to lined writing paper, except the "lines" are watermarks.
The 2nd printing were only dos reales stamps, imperforate and serrated on each type of paper described above.
