Wordless Graphic Novel

[Moonbat]

Hi

Does anyone know of any graphic novels (or comics) that are completely dialogue free, and even word description free?
I know about Marvel's short period of no dialogue comics, but I'm wondering if anyone knows of something further.
A friend of mine said she read one once, it was set in the amazon (maybe) and was about a woman who had lost her child, but it had no words what-so-ever. I'm wondering if any of you guys/gals may have an idea of what this graphic novel was/is?

There are some... there's one called Gregory, I think, and others that I can't... remember... *

There's Shaun Tan's Arrival and and Flood by Eric Drooker, which I've read.
