Interesting, both the cardstock and ink are totally dead under longwave UV.
I'm thinking it's real, but I'll hold off till I figure out fixing my big UV light which does both short and long wave. Technical stuff follows, if it bores you stop now. US stamps only react to shortwave UV, while most other things react to longwave. I tried a few other items, and it looks promising, but not conclusive 2011 topps -reacts 2011 Topps allen and Ginter - do not react! 1981 topps - cardboard does not react, yellow ink does. most envelopes - react T206, real allen and ginter,e90-1 --Do not react.
