Cruising through my stock books, as I usually do, I noticed a Large Queen mixed in with a mess of Small Queens. And consulting Unitrade (2011) it appears that it is a 30e. The stamp corresponds with the pictured 30e, but the description states deep blue. Unfortunately, there is a crease running diagonally thru the upper left portion of the stamp.
Just a bit confused between the pictured 30e in Unitrade and the description.
