Forgery.

Many covers were "artificially treated" to give the impression they were genuine. Sometimes original stamps would be soaked off and a Charity stamp affixed and "cancelled".

In the example shown here and in the detailed scan below, it is clear that the two cancellations are of different format and size.
Also the cancellation on the ½d green is clear of the Charity stamp which may be covering a space previously occupied by another stamp.
