Malcolm Barter is listed as the interior illustrator for The Forest of Doom, the first Fighting Fantasy book I must have read (I think I was about 9 or 10). Some of these images have remained with me ever since; they seemed incredibly grown-up to my primary school mind - in a stratosphere of sophistication in comparison to the cartoonish things I had been exposed to in kids' books.
Here are some favourites:
Now, what strikes me about them is their strange combination of understatedness and detail. Barter's world is grimy, lived-in, stark: it concedes nothing to modern nerd-dom's insistence on all-awesome, all the time. What you see is what you get. These pieces do not, like a modern D&D piece, depict larger-than-life heroes who the viewer is supposed to fantasise about becoming. No; they depict a real, inhabited world, with all its flaws, disappointments, sorrow and bathos.
I'm curious to know what happened to Mr Barter. Biographical information on the internet is scarce. Something about these pieces suggest that, given time and money, he could have produced work of (even more) exquisite skill. Yet he seems to have subsequently disappeared.
