Skywald Artwork

In Jim Warren's mind, Skywald Publications was his chief rival. Well, it's an assumption because Jim didn't seem to like anyone having the gall to publish a magazine next his!!! I loved the Marvel/Curtis titles---but the Skywald's were edgier---more violent and over the top. In many ways, in overall excellence, I would personally rate Warren's crop superior---especially in writing. But Skywald did use a fair amount of Spanish artists that either never or seldom worked at Warren. In my 35+ years of actively collecting original, I have seen very few (if any) examples of artwork from the Skywald stable. That includes zero line art--and very few covers. Anyone have a lead on any--I'm all ears---but I think much if not all of it is either gone, or (covers-wise) in Spain. But I'm still looking....
