A12 1st royal mail red - forgery ??

  • this LW reaction appears on flourescent or varnish inks
  • as I review my collection, I am finding similar reactions on other machins

  • the MBPC  auctions note bright and dull phosphors on booklets, but nothing like the all-black above
  • Deegam HB4 gives no mention to phosphor strength, or missing phosphor on any 1st royal mail red
  • I reserve verdict on these...
  • comments welcomed.
could this be from A12 Alice booklet ??
