Yes We Kern!

I found these posters by Stefano Joker Lionetti on Behance (although I don't remember exactly how I found them...). There isn't a lot of other information on them, but they just really stand out to me.

They are typographic posters, and from what I can tell (from the last one at least) they outline and show different typographic rules and principles. There are 5 different posters in all.

The different extreme weights of the typefaces from the ultra thin to the ultra heavy in combination of the large area os white space really make these posters stand out. Add in the color palette, the strong diagonal composition,  and the copy on a strict grid and you've got a great poster. Doesn't hurt that they also have great sayings on them. YES WE KERN!
