Canada Limited, on JAC Paper (Canada) papers<br />

and both stamp series showed considerable<br />

variations in stamp paper fluorescences. Some<br />

self-evident questions are: Why is there so great<br />

a variation in the stamp’s paper fluorescences?<br />

Are the variations in stamp paper fluorescences a<br />

manifestation of the paper, the self-adhesive gum,<br />

a reaction between the paper and the self-adhesive<br />

gum or of the printing process used by the<br />

Aston-Potter Company? Why are different paper<br />

fluorescences being used in stamp production?<br />

Are these varying paper fluorescences a deliberate<br />

or an accidental characteristic of the stamp paper<br />

production? Is it only JAC Paper (Canada) papers<br />

that display variations in paper fluorescences? Are<br />

these varying paper fluorescences a deliberate or<br />

an accidental characteristic of the production<br />

of JAC Paper (Canada) papers? How can the<br />

different fluorescent papers be identified on<br />

unused stamps in unopened booklets? How can<br />

the different fluorescent papers be identified<br />

on the self-adhesive stamps without destroying<br />

the integrity of the booklets? If different paper<br />

fluorescences are deliberately being used in the<br />

production of self-adhesive stamps, can we, the<br />

philatelic community, accurately determine the<br />

ratio of different paper fluorescences used in the<br />

production of these stamps?<br />

If different paper fluorescences are accidentally<br />

being used in the production of self-adhesive<br />

stamps, then are these varying paper fluorescences<br />

identifiable as EFO’s? Should the stamp paper<br />

fluorescences, either by deliberate design or<br />

by accidental EFO’s, be endorsed in the stamp<br />

catalogues? Should stamp paper fluorescences<br />

command a premium catalogue value based<br />

on the relative scarcity of the different levels of<br />

fluorescence? How can the relative scarcity of<br />

the different levels of fluorescence be accurately<br />

determined other than by a carefully orchestrated<br />

scrutiny of used stamps and repeated replication of<br />

that analysis? <strong>The</strong>se and other questions beg to be<br />

answered.<br />

I welcome discussion and observations concerning<br />

this research, and would particularly like to receive<br />

notification of your replication of this study, and<br />

your test results. I can be contacted, either directly<br />

or by letter to the Editor, through the editor of this<br />

magazine. *<br />
