Spanish Civil War - FAKE postage type

A rush purchase led me to buy this fake before I did the research, it was cheap and so was I. Spanish 30 Centavo (scarlet) which I presume to be real on a fake cardboard similar to authentic pieces. It's obviously in too great of shape to be authentic. Presented here as a lesson learned and a chance to post this monograph on the series.
