That river in Egypt

"This is Necronom IV, painted by H.R Giger in 1976. I'm pretty sure that's what it's called and when it was made, but the Wikipedia image is different to the image I have. But it's very similar, so I'll go with it. Necronom IV was the painting that formed the basis of the design for the Xenomorph in the Alien movies. I don't know about you but it's a big dickhead"
