I had a poster in the early 70s, done in a realistic style, that depicted a handsome, young human with large wings, standing, I think, on a craggy peak. But one of his shoulders was injured, and underneath the torn flesh was a shoulder joint made of metal. As a teenager, I thought this was profound and angsty. Anyone know the painting? The artist? Thanks in advance.
Frank Frazetta was one of the more prolific of that genre, but your description doesn’t ring a bell.
Pretty sure, not positive, it wasn’t Frazetta. The figure was not exaggerated in his notable style, and I don’t think it was from a book cover. Could be wrong, it was a long time ago, and when I was young and irresponsible, I was young and irresponsible…
And the other big name fantasy artist of that period is Boris Vallejo.
Frazetta didn’t do a lot of cyborgs, either. Vallejo is a good thought.
I’m no expert in the art of Frazetta or Vallejo, and they did a ton of work, but as I recall the picture, it was more subdued, if that isn’t a little silly when talking about a winged humanoid cyborg…
call a comic book shop during business hours and ask
Do you remember why it was a poster? Was it from a movie? An album release?
The version I had was just a poster, no words or indication that it was from an album or book cover. Of course, it might have been. And I think there were others, either by the same artist or in the same style, not in the warrior or super-gluteal style.
The only other fantasy artist of that era that I recognize is Roger Dean, and he’s a lot more surreal and a lot less cyborg warrior than the description.
Actually, I’m reminded more of X-Men by that description than any 70s Fantasy stuff.
Did Archangel have adamantium bones?
Archangel had metal wings, not metal bones. And that was in the 90s. In the 70s he was just “Angel”, lamest of the X-Men.
So many to remember…
I may have gone down a cul-de-sac by calling it fantasy art. It didn’t look at all like Dean, et al. The human figure was more like the statue of David in proportion and musclature, and more of a tragic than a heroic figure. The background was bleak, with, I think, lots of orange and blue and gray. I promise to let it go after this note.
Maybe Michael Parkes. My daughter loved him. He was known for realistic depictions of unrealistic stuff.
Closer in style, but not him. O Straight Dope, why hast thou forsaken me?
This was starting to really bug me. I was sure I knew the artist the OP was talking about, but didn’t know his name, and couldn’t figure out a way to Google his art. Turns out, it was Michael Parkes! So my question has been answered. Hard cheese to Kropotkin, though. 
Some of Carl Lundgren’s work looks a bit like the style and colours. This, for example, though it is cute, not existential and profound in a way that appeals to a teenager wallowing in whatever it is they wallow in
I don’t see any images that seem to match the description, butMichael Whelan was active in the mid-seventies.
