Each numbered leaf has one of Emanuel's sketches affixed to the recto, versos blank. 60 of the sketches are original unpublished captioned pen and inks, while the remaining 4 leaves contain published sketches. Six of the seven loose sketches are numbered 65-70, suggesting Emanuel intended to add them to the volume.
