The scroll (almost certainly hand-bound) is bound into a book, of which I would guess perhaps only few were printed. The cover of the book is printed, but the spine (original) appears to be hand-written and the book states it is for the Department of State and Justice.
The scroll bears the seal of the Emperor of China, and by looking at the back of the scroll you can see the seal appears to have been printed using a woodblock print. According to a Chinese friend, it is only the Emperor of China who employs his seal. No one else in China would have permission to use it and certainly no one in Cuba. In my opinion, the seal would have had to be applied by hand (and the back again seems to indicate it was a separate process from the printing entirely).
