The copies here are from resized reprints so, sadly, far below par.
Jesus Blasco made the Steel Claw my favourite character when I was a kid. I couldn't understand how he drew the way he did, just that it all seemed so real.
An interesting side note-- the four tier layout of the pages was to allow the art to be cut, hinged and folded along the horizontal gutters ( I have never seen a title page so I don't know how that was cut.) I was once told that the pages were treated in this way to avoid some sort of import duty when Jesus Blasco, living in Spain, sent the art to the UK-- But if anyone knows for sure I'd be interested to hear.
The scan of a cover painted by Jesus Blasco was sent to me by Jaume Vaquer who has also posted some of the very nice original art he owns at: -www.comicartfans.com
