I came across these unofficial Black Swan Posters a while ago! Seeing as Black Swan, with Natalie Portman, came out mid December 2010! But I have only just been able to research into the artist behind them! La Boca is an “independent design circus specialising in art and design for the film, music and fashion industries.” I was left in awe of these pieces of work! Hope you enjoy them too! I love the modernist take on these posters. I hope I can produce something as beautiful soon.
I like these in comparison to the official Black Swan Poster like the one below.
