Hi, I'm a long-time SF reader and collector (2500+ items). Part of my collection consists of Dutch translations.
You can find some of my cover scans at Flickr.com. Feel free to copy them (resized to 600 dots) for cover art on isfdb.org. Everyone else does (see Pinterest, Tumblr, etc).
I'm currently spending most of my time here adding cover artists to publications. Much remains to be done in this area.
I've got a few dozen sf art books to aid me, starting with:
- Patrick Woodroffe - Mythopoeikon
- Peter Jones - Solar Wind
See also SF art book tag.
Some artists to add:
Angels and Spaceships, Four Square 1962 - Josh Kirby - acc to Kirby checklist.
Tarzan of the Apes, Four Square 1967 - Josh Kirby - acc to ha.com and Kirby checklist. More than a few other Tarzans are on that checklist
Untouched by Human Hands, Four Square 1967 - Josh Kirby - acc to Kirby checklist.
S Is For Space, Pan 1972 - Ian Miller - based on style and acc to tikit.net.
A Maze of Death, Pan 1973 - Ian Miller - acc to comicartfans
Nightmare Reader Vol 1, Pan 1976 - Alan Lee - acc to Stephen Jones, WFC 2013
17th Pan Book of Horror, Pan 1976 - Alan Lee - acc to Jones, WFC 2013
Other Days, Other Eyes, Pan 1978 - Stuart Hughes (artist) - acc to Welshgriffin, see Flickr.
Suaine and the Crow God, NEL 1975 - Ian Miller - acc to comicartfans.
The Green Girl (Avon 1950) - Ray Johnson - acc to some internet sites, source of attribution unknown.
An Earthman on Venus (Avon 1950) - Ray Johnson - acc to some internet sites, source of attribution unknown.
The Princess of the Atom (Avon 1950) - Ray Johnson - acc to some internet sites, source of attribution unknown.
The Secret Visitors, Ace 1957 - Ed Valigursky - acc to style and munchkinpress.com.
The Space Willies, Ace 1960 - (Arthur?) Renshaw - acc to signature on this copy at Flickr (link corrected 2019/03).
Rebels of the Red Planet, Ace 1961 - Ed Emshwiller - acc to munchkinpress.com.
Outside the Universe, Ace 1964 - Ed Valigursky - acc to comicartfans.com.
Crashing Suns, Ace 1965 - Ed Valigursky - acc to munchkinpress.com.
Moon of Three Rings, Ace 1970 and 1974 - John Schoenherr - acc to Andre Norton site. It would be nice to find a copy of John Schoenherr SF Checklist...
Secret of the Lost Race, Ace 1971 and 1974 - Josh Kirby - acc to Kirby checklist.
A Trace of Dreams, Ace 1972 - Davis Meltzer - based on style and the signature 'DM', even though Meltzer usually signed with 'Meltzer' or 'Davis Meltzer'.
The Galaxy Primes, Ace 1976 - R. deAnda - acc to signature, compare to Noah II.
Naked to the Stars (Ace 1980) - Enric - Original art at ha.com shows signature 'Enrich'.
Seven from the Stars, Ace 1962 - Ed Emshwiller - There's very similar preliminary art at ha.com credited to him, for comparison see here at Flickr, or see Ace Image Library.
The Sky Is Falling, Born Under Mars and The Best from Fantasy and Science Fiction: 19th Series (all Ace 1973) have the same not quite readable signature, something like 'PDRICK'. Based on style, Envoy to New Worlds, Perry Rhodan #43, PR #44 and PR #48 are painted by the same artist.
FMA appears to be a signature of Franco Accornero, according to several art sellers. Which makes sense, since signatures FMA and Accornero are both found on mid-1970s Warner paperbacks. Someone who contacted me on the previous statement, wrote me later that he'd mailed Accornero, who confirmed he was FMA.
On the other hand, some ISFDB cover art attributions I doubt:
Through a Glass Clearly (Four Square 1967) does not look like Josh Kirby and is not on Kirby checklist.
The October Country (NEL 1970) does not look like Josh Kirby and is not on Kirby checklist (despite credit in SF Monthly).
Citizen in Space (NEL 1969) is on the Bruce Pennington checklist, and does look like rudimentary Pennington. Strike that AbeBooks credit to Ronald Ferns.
20 Million Miles to Earth is not the exactly same cover as on the Italian translation and is of course not by Luigi Garonzi (probably by Ed Valigursky).
The Pawns of Null-A (Ace 1956)'s style points to Ed Emshwiller, not Ed Valigursky. A vague signature EMSH appears to be visible at high magnification.
The Dragon Masters (Ace 1972) does not look like Josh Kirby and is not on Kirby checklist. The stippling suggests that the artist may be the same Lloyd who provided the flipside. (Where does this Lloyd come from? The stippling also reminds me of early Brian Froud ?!)
The Sound of His Horn (Ballantine 1960) is currently credited to Richard Powers, but acc to ha.com this should be (Robert) Blanchard.
And Some Were Human (Ballantine 1961) is currently credited to Richard Powers, but acc to ha.com this should be Ralph Brillhart.
Fire Past the Future (Ballantine 1960) is currently credited to Richard Powers, but also looks like the work of Blanchard.
I also have doubts about Turn Left at Thursday and The October Country (Ballantine 1964).
And The Diabols is credited to Powers, but looks a lot like this cover by Tom Adams (cover previously used on Oddities, another Paperback Library cover from 1969).
Where did Jane Frank get the Powers credits from? From abebooks.com?
5 Unearthly Powers (Fawcett Gold Medal 1965) looks like Jack Faragasso's work. Powers is NOT even credited for this in The Art of Richard Powers.
Masters of Everon (Ace 1980) looks like Vicente Segrelles, not Enric.
Cryptozoic (Avon 1977) - Obviously painted in the style of Dean Ellis, so the credit (remaining from an earlier edition) to Don Ivan Punchatz should be removed.
A note about munchkinpress.com (The Illustration Exchange): The site is now only and not quite completely to be found on archive.org. A sad loss.
