I tried to make a poster with hand drawing for giving it human touch.
For the composition, I used grid and kind of golden ratio, which is 1:1.618 but not accurate way.
The ratio between full length of the poster and the end line of grid is 1:1.43.
And to emphasize this poster is from itp, I use black and white except the itp logo, and all the informations are hand written but the logo.
first idea for the poster
