The task is creating a Gig Poster (of a band and place of our choice). So after some photoshop tricks to make the poor baby wear the headphones, I've started to do the grunge effects.

some half-tone effect

using a copy machine I took a copy of the copy, and then again. after 4 times the result is good enough.

The finished poster!

and a mockup! the poster is 50X70 cm
