I looked the matter up on Wikipedia and went round in circles on there for a while but in the end do think that it was by Pierro......although I am kind of keeping the door open on this one.

In this sandpaper plate the lighter figurative plate is cut out from a sheet of "drypoint paper" which I purchased ages ago from Intaglio printmakers suppliers in London, UK. The product is designed for beginners in printmaking. I can also imagine it being used in classes for the general public to give them an experience of making an 'intaglio' print.
Here is a LINK to another print/plate where I first used some drypoint card onto a plate to get a particular 'ghostly' or rather 'soft-edged' effect.


Having said all of this......I dont think it is a particularly good example of this technique. I can not remember where it was, that I came across the idea.
