Since the 1950spaper productscontain large amounts ofphosphors, chemicals & bleach that would make it fluoresce brightly.
Repairs, alterations, most tagging & glues would also show up. IF YOU ARE A STAMP COLLECTOR
& are buying this for your hobby, be sure to let me know; I will send you attachments in an email as an added bonus.
I have several interesting & informative articles on Taggants & Chemical Additives on stamps & the paper they are printed on.
I do not send this out automatically.
