The first thing necessary is to get permission from each photographer (or whoever owns the photo) to use the pic(s). That would be the biggest part of it. Though I did this poster for fun for myself, I also do this kind of work professionally and getting the "license" to run copies would be mandatory if we were to make them for distribution.
I suppose I could start from scratch and ask every owner whether I can use their pics or not. Either that or have those who dont want their pics used, to contact me by e-mail within a given time frame. :wtfr2:
Next would be the actual cost making each poster. And there are a few other considerations in between.
It would be cool to do though...;Dr;
