In the 60’s I bought a pad of drawing paper, cream colored, clay coated. I believe it was Morilla Cameo, a paper that was used for silver point. I’ve never found anything before or since as wonderfully responsive to pencil… or to fine ink. You could use pencil as you would use a fine pen nib with ink… with all the shading and modulating power of pencil.
Here are two drawings, the first, from 1969 (crow quill), the second, from 1970 (pencil). I’ve searched in vain trying to find paper like this. If you know where I might find it, please let me know.
Post script: my suspicions were right-that this paper was intended for SilverPoint. Here’s a wonderful site with information on technique, materials and contemporary silverpoint artists.
