An interesting destruct, while giving an idea of the printing technique used.
The print with dark purple colors is an intaglio, but most likely its fixed components (denomination, figure) were a previously made "general", "universal" matrix on which were added depending on the issue (banknotes issued on different annual dates) the date of issue and the signature current for that date.
Here you can see that the addition of these components flawed. Perhaps too shallowly added to the master die? Or perhaps the printing of these components took place in another "machine movement" and here the printing element ran out of ink?

While perhaps not impressive in its efficiency, it is an interesting type of destruct.
