We saw some really good stuf on the Picture Systems Blog by Zach Ohora. Like this illustration called Wolfpack. You should also take a look at his stop snoring bernard.
Sure, not all posters have to be printed. Like this paper tattoo by Jacob Dahlstrup Jensen.
Some pixel goodness for your walls. By Physical Fiction. This pixel play of words is definitely my favorite. To bad it’s sold out (as you can see). Some other nice prints are still available for sale though.
Vibrant colors and looks like fine quality printing too by MIKE PERRY @ LANDFILL EDITIONS
Something cheerful to compensate for the gloomy weather. Balloons alway do the trick. By Ingela P Arrhenius.
Nice abstraction by Lauren DiCioccio for sale at 20×200.
We came across a very nice print by Geoff Mcfetridge @designsponge. That definitely made us want to check out more of his work. So we did, and we liked it

Ssome nice colorful artwork by Marcus Oakley. Some stuff really takes youback to the 70ies. He also has a really nice series of band-portraits, all of them well known from your parents record collection.
Wow stellar stuff! Ben Newman really has a really good retro thing going. When we first saw this we thought that is was something from the fifties. The Solar System Poster.
Marcus Walters‘ take on a poster for the lovely Studio Ghibli movie Spirited Away.
Check out this poster from American designer Patrick Leger (more nice work there). It’s for sale at his store.
Really nice pattern inspired by the Indonesian volcano the Krakatoa by Studio Violet.
Posters and other nice silkscreened goodies by doctorpizzoli on Etsy.
