You are buying ONE single example of this error.                                                                                                                                                                                                                                                                     Note that care is needed to ensure the greenish blue is completely missing. Partials and weak printings exist. The genuine error has the value in pure white.

This example also has an additional error. There is a very thin deep blue (?) line running vertically. This runs from top to bottom of the stamp just to the left of the Queen’s earring.  We cannot find any mention of this anomaly in either catalogue.
