Posters For WWF India How It Works: From a distance you can see endangered animals in the poster, but when you go close they disappear, Its a very old illusion trick but it works like a charm and gets the message across effectively. The camera actually cant focus on the lines properly so the Images are not very clear, so i had to photoshop it. Please bear with the distorted images. Hope you guys like it. The Headline in the poster says " The Closer Man Gets, The Faster they disappear".
