Since 1998 I have designed the posters for the annual missions conference at my church, New Covenant Presbyterian Church in Abingdon, MD. (http://ncpres.org)
Each year we try to capture visually the main message of the conference which is typically set by the keynote speaker. Sometimes I have had only a few days, or a day, to get these done.
