The luminescent tagging series is one of the most popular and highly attended Stamp Chats that we have hosted to date. This three part series has drawn in hundreds of attendees, all eager to ask our guest, Mr. Henry Jehan questions; savoring each slide and requesting that his slide shows be made available. One email we received even requested that a "Luminscent Tagging" group be formed so collectors could continue the conversation!
In 1963, Henry Jehan was a high school student taking classes in physics when he learned of an experiment being run by the Department of the Post Office. They were printing stamps with a special ink that would glow under specific frequencies of ultraviolet light. He saw this as a perfect melding of his studies and his hobby, sparking his lifetime interest in the luminescent tagging of postage stamps from their very beginning.
According the response from this series, there are a number of you out there who hold the same enthusiasm and passion for luminscent tagging. As such, Mr. Jehan has generously offered his slides from the three part series:
Luminescent Tagging Part I - Expermintal Years
Luminescent Tagging Part II - Technology Evolution
Luminescent Tagging Part III - Hidden Art
Additionally download the handout related to this series: Luminescent Tagging Handout
