- 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 ??
