    Of those issued in 1974, only the 90 øre red was also issued on ordinary paper. I think the fluorescing agent may be water soluble so if the stamp was left in water for a long time it may have "washed" off.

    I have heard of a collector who stored a collection of Danish stamps in plastic sleeve pockets. The plastic sleeve pockets were from the 1970's or 1980's and not copy safe, there was a chemical reaction over time with the fluorescence of the postage stamps. Result was the fluorescence was transfered out of the paper into the plastic.

    Dear Sir

    The stamp depicted on your envelope is from Norway. It is Norways first stamp with Shilling denomination. It has been cancelled in Drammen a small town just outside the capitol city Oslo. It is a valuable cover.

    Sincerely Mr Göran Lif Stockholm Sweden.
