(25 c) There are three papers: the ordinary, another white paper, but slightly luminous under the quartz lamp. Then, the good, No. 1331 d (Y. & T.) that is really fluorescent yellow under the quartz lamp.
As for the 30 c. there are two papers, simply a set a little bright but it is neither luminescent nor fluorescent.http://www.alex-bernardini.fr/Coq-g...62-1331.html
