Sesame Street comics from Spain

Does anyone here know about these?

They were released in the late 1970s, written and illustrated by Spanish artists A. Albaran (sp?) and Antonio Perera. There were even translated versions available in Dutch, German and Italian. I've seen bits and pieces of them in different places online, and from what I've seen, they look impressive. I'd love to find complete issues (there were 22, though it looks like they continued with a new series later on with the Spanish Muppets Caponata and Perezgil in addition to the American Muppets, as seen here: http://www.todocoleccion.net/ediciones-recreativas-barrio-sesamo-n-5~x26414085).
