The image below of the back cover shows some detail of how the binding is fastened. There are what appear to be hand-drawn arrows illustrating the direction the leather strapping is inserted. There also appears to be a waxy substance on the leather perhaps to secure it in some fashion.
  You also find a hand-drawn 5 triangle motif fashioned in a trapezoid shape. This motif appears on a number of Woodward's drawings from 1902 to 1908 and is ultimately a logo of sorts. At its most basic level, it is a cleverly concealed "W" obviously for "Woodward." In this example, the upper left triangle is colored in but none of the other examples in which this symbol appears have been shaded. Is this another example of Woodward's inconsistency in  the  assembly  of  this  booklet?  Was this  intentional  or  did he

simply forget to finish coloring the other triangles? As deliberate as we believe Woodward to be, there is little in this booklet we can say for certain was deliberate other than his obvious choices.
  There seems to be great importance to Woodward in having a logo or brand. An emblem that represents him. After all, his professional signature with its red "S" is a branding of his name emphasizing his middle name "Strong." The more remarkable thing about this 5 triangle motif is that we are discovering it has a strong symbolic relationship to his red "S" he used as a professional landscapist. Again, we cannot say for certain if this is merely coincidence lent to the powerful subconscious or a deliberate choice on Woodward's part? In all likelihood, it is a little of both. Stay tuned for more on this at a later date!
