Luber, Forensic Document Examiner (Diplomate, American Board of Forensic Document Examiners), using VSC2000 and Stereomicroscopy in 2011. Note: Special attention was directed to the white-yellow gum on the back. All three made a determination that the gum on the back was original. PF said, “Using side lighting the gum was viewed at several levels of magnifications. The consistency of the cracking matched gum on stamps of that age. Regumming was not evident” and concluded that “it was original gum.” RPSL stated that it was not regummed and that the gum remaining “is original to the stamp” LUBER stated that there was “no visible trace of moisture activated gum on the front or front edges of the stamp” (traces of which are generally found on regummed stamps) This lot is sold solely on the basis of the Philatelic Foundation and Royal Philatelic Society certificates only and is not subject to reclamations.
