Based in Berlin, Bartholomäus Zientek is a German graphic designer. The award-winning artist has amassed a huge collection of sketches over the years: composed of doodles made in quiet moments, often in monochrome, and he draws on them for projects – “I would say black and white is kind of raw, pure, cool, rebellious, confident. It’s a strong decision. There’s nothing soft about it, no compromise between these two extremes, he says.” We featured Barthomomäus’ work as part of our series Your Work Here: a massive open call to WeTransfer users to submit their artwork on the theme of “black and white.”
