ALL HALLOWS POST OFFICE 2020 (FarFetchedPhilately)

Moving on to the monochrome Death of Stamps. These were not available as a sheet and only appeared in the packets.
There sems to be four different stamps based upon the degree of illumination of the skull, which for the moment I am calling 100%, 75%, 50% and 25%. I have reversed skull variants of the 50 and 25, and have no reason to not suppose that the same applies to the 100 and 75.

I have examples of the 100% from bottom left corner and 25% from the top right. The marginal 25% ruins my first guess that these were printed in rows from 25% at the top to 100% at the bottom. Perhaps they were just randomly placed on the sheets.

But I don't think the 50% image has a reflected image. 

I think the death of stamps sheet looks something like this

I am well aware of the assassin's Guild stamp. DW has used overprints on a large number of occasions, all look as if the were pinted with the stamp but made to look as addition. Other full sheet examples include the Shades halfpenny surcharge and the Bugarup University. Both these have the 'overprint' variously rotated and under-inked in places.

Returning to the Death Duty overprints, most of the variants were from the first printing of 2020. These were the duller coloured (by comparison) ones. Repeating the earlier image, this one has the crucual selvedge dates.

For me, however, the easiest way to distinguish between the two printings is to look at the reverse. Two different papers were used and the 2020 first printing has a slightly cream colour compared with the whiter 2023 printing. I have tried a scan of these, but the difference just doesn't show up.

Here are the 6 variants of the overprint

The top one is the 2020 sheet variant - faded red -45 degrees
Then three non-sheet 2020 variants
Faded blue +5 degrees
Bold deep purple +5
Faded blue -5
And the 2023 sheet variant - bold red +5
