This series had covers which were linen with pictures that were continuous between several different books. A number of different linen swatches were used for the covers of the books of this series. Since the swatches were larger than was needed for the covering of a book, a number of different covers for each swatch were possible. Certain pictures are much more uncommon than others. Today I found a second picture from sw-7 (See: http://henryaltemus.com/series/series57.htm). As you can see pictures overlap to a degree. I do not know what the complete picture for this swatch will look like.
