Great work too bad it was never uploaded (especially the full color version)
here a sample of old b/w version /g/637126/db1f339d80/ (the b/w have 4 books not 6 as the full color, I don't know if this is because the full color have extra pages or simply a full color book is smaller than the b/w book).
You can see more sample pages here (I was not able to extract them for uploading, sorry)
