I am no graphic designer. The graphic designer I asked on the phone was… busy.
Having done some pushing characters around, my versions differ only slightly. But they got successively better. That poster was made from a Pages template that came with the app.
Something about the poster is crap. Can’t put my finger on it. Probably something with the body text. But, as it states its business quite clearly, I’ll go so far as to say I’ll post it publicly.
