The Museum of Forgotten Art Supplies – Drawger.com:
Welcome to The Museum of Forgotten Art Supplies… where tools of the trade that have died or have just about died a slow slow death are cheerfully exhibited.
Due to severe government budget cuts to the arts, our little museum’s acquisition funds are frankly, well, bupkus. So, we welcome Drawgerers to submit images of any artistic tools, machinery, gadgets, etc. that they feel have bitten the dust.

Ahh – this takes me back. I didn’t see them here, but I remember using “Artist Greys” (a set of grey markers in various shades) to practice retouching B&W photos when I was a kid.
