Roses By Tony Edward Agnes, Champlain, Morden Centennial and Canadian White Star have fascinated me for some time but it was not until I recently received over 100 of these stamps in a bulk stamp purchase that I was able to experimentally demonstrate the interests that my existing accumulation had instigated. The stamps were printed in se-tenant panes of twelve stamps in Booklet 245 by Ashton-Potter Canada Limited, on JAC Paper (Canada) paper, I had for a long time suspected that these stamps were printed on stamp papers with differing levels of fluorescence. My existing hoard of 307 stamps showed three distinct levels of paper fluorescence: 65% E-4, 12% E-5 and 23% E-8, as shown in Figure 1, but I had soaked these stamps, in small quantities, from envelope pieces in the distant past. I had not, at the time of soaking, recorded the fluorescence of the carrier envelopes from which my hoard of stamps had originated. Caution would suggest that the variable fluorescence of the stamps could be the result of fluorescent contamination from the carrier envelope pieces during the soaking process. Additionally, careful study of the fluorescences of my existing stamp hoard created some doubts in my mind. Although the levels of fluorescence shown by the stamps divided into the three distinct groups on my “E-Scale”, the E-4 stamps displayed a slight mottling of the fluorescence, while the intensity of the E-5 and E-8 fluorescent stamps was somewhat variable across each of the individual stamp: displaying a marble like appearance with whorls of faintly lighter and slightly darker fluorescent intensity. Some stamps with Dextrine or PVA gum adhesives that I had observed in the past, having been poorly soaked from highly fluorescent envelope pieces, had absorbed fluorescent chemicals from the envelope pieces and showed variability of the fluorescence across the stamps similar to my hoard of E-5 and E-8 Roses stamps. The resulting fluorescent contamination of these stamps, using the Dextrine or PVA gum adhesives, created a false impression of fluorescent stamps. It was the simple fact that I have established in the past that the modern pressure sensitive gum used on selfadhesive stamps appears to be quite impervious to even a harsh chemical like iodine (see: “Paper Fluorescence of the Self Adhesive Flag and Iceberg Stamp.” The Canadian Philatelist. March/April 2006. Vol. 57, No. 2. Page 77.) That convinced me that the variability of the fluorescence of the Roses stamp papers might not be from envelope contamination. Armed with a supply of 138 new test subjects I was now able to devise an experiment to prove or disprove my conjecture that the Roses Booklet 245 stamps were actually printed on papers with three different levels of fluorescence.
