 I really like this note. It's great how the serial numbers were added without noticing the complete face is missing.

 There are three distinct causes for a missing printing error. Most commonly, two uncut sheets of currency stock enter the printing press simultaneously with one atop the other. The uppermost sheet accepts the imprint normally while the lower sheet-because it is protected by the top layer-passes through blank. Less frequently, an entire stack of sheets is advanced to subsequent printing and/or cutting operations after skipping a printing stage.
