I found this beautiful stamp from Spain in a collection that I bought last year from a German auction house. It is one of the first six stamps, that were issued in Spain on 1. January 1850. It shows queen Isabella II and the denomination is 6 Real. As you can see from the picture, it is in perfect condition (LUX). CV is: 850 €, and it was sold at a Norwegian stamp auction for 2.600 Nkr., approx. 250 €.
