JOC International is the publisher who released the Spanish-language versions of Pendragon. Joc was the first publisher to translate many foreign RPG's in Spain including Call of Cthulhu, RuneQuest and MERP They also published Aquelarre, the first professional Spanish RPG.
I hope the illustrations are sufficient to satiate your curiosity, and that you can translate the titles to their English counterparts. If not, just enjoy the pictures!
My thanks to Carlos de la Cruz for these scans.
