Emma, nude on a staircase, one of his most famous works he ever painted, and he took on geometric abstraction with his colour chart, influenced by his friend Blinky Palermo, but also influenced by pop art and minimal art. Richter had already been experimenting with abstraction and minimal painting, think of the abstracted blur or washed out zones of oil paint, but also depicting very minimal elements, such as curtains, tubes, turning sheets or daily objects. The colour charts were copies of paint sample cards, which paved the way for Richter's future abstract paintings. After Emma, nude on a staircase, Richter would paint several erotic nudes in 1967, followed by cityscapes, aerial views, mountains, starscapes, clouds, seascapes and landscapes in 1968 and 1969. With these artworks, there is this notion of both an almost nostalgic romanticism and an ongoing exploration of abstraction. He would paint many shadow pictures, corrugated iron as a geometric abstract work, grey monochromes, colour streaks and grit, arriving at pure abstraction and questioning the limits of representation. By the end of the decade, Richter had established himself as a contemporary artist, participating in group exhibitions across the globe. In 1969, he was included in the exhibition Nine Young Artists at the Solomon R. Guggenheim Museum in New York, his first show at a major institution. However, Richter was still unsure about his future and in search for a specific direction, so his paints and the experiments would continue.

and then they built this corrugated tin structure on top as well to, I guess, protect where I'm standing from rain.

It picks up corrugated cardboard from the left rack, and is doing a box to pack it.

These shantytowns—poor communities where the houses are built out of cheap materials like corrugated iron and plastic sheeting—are often off the grid.

And while he continued to use the traditional methods using the turf and the lava stones for the walls, he did use corrugated iron for some of the front walls and some of the newer roofs.

So whereas a gasoline car really just has thin corrugated sheet metal at the base and can't transfer the load in a side impact.

The people there lived in corrugated tin shacks with no electricity, no water, no toilets.

We're walking down a small alley, and this is actually a corrugated roof.

It's just basically an aluminum box with corrugated metal along the outside, the occasional window, and that's it.
