Here are some 1914-1915 Spanish cards and a 1912-13 (I think)
The Roma Forns is from 1912-1913 or the year after, I believe. 1913 is the last year that he played.
The others include team cards of Espana and Irun, as well as an action card of Armet and Belauste (played for Spain in their first Olympics)
These are some of the earliest Spanish cards that I have been able to put my hands on.
