The 4d Guernsey (Plain) Printed On Cream Paper ?

It's most frustrating when you come across a variety of stamp that you have found, only to find that it is not listed, even after looking in a specialised catalogue for it.

This was the situation I was confronted with some years ago when finding this 4d Guernsey (plain) that has apparently been printed on a cream paper.

This particular stamp was first issued on the 7th of February 1966 and according to the information given in the catalogue with reference to the types of paper used, this cream paper version should not exist and only whiter ones should be found as per SG's introductory notes .........

Here are 2 unmounted marginal pairs as seen in the normal spectrum, the cream paper version being on the left.....

Followed with the same stamps, but as seen under longwave ultraviolet.

According to the figures given there was a combined total sold of 4,415,040, just how many was printed on this cream paper is an unknown factor as in theory it does not exist.
Or does it ?
You decide! WM

Philately begins, where the catalogue ends.

As detailed in the GB Specialised Volume 3 'QEII Pre-decimal' Stamp Catalogue (13th Edition) 2019 edition:



Suggestion:

Find other people with a similar interest, form a study group, publish a paper. Only when there is a demand from collectors for such material will the catalogue editors consider it.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If a variety or error is not listed in a specialised catalogue, collectors will not be aware of their existence and consequently there will be no demand.

The editor of a catalogue will not list an error or variety unless there is a demand, reference (your quote)

The above creates a catch-22 situation.

This posting is to give evidence of their existence and make collectors aware of a specific unlisted variety, in order for them to create a demand. WM

In my opinion, increasing the knowledgebase is a good thing but it makes little difference if something gets into some catalog or not.

mikyh......... May I also point out that the paper fluorescence notes you displayed from your SG 2019 Vol 3 specialised catalogue are incorrect as it states that fluorescence should be viewed using short wave UV.
In order to assess paper containing fluorescence one must use long wave UV. WM
