Please write your briefs correctly before giving them to a designer. Believe it or not, but we actually use these letters & words on a page as an outline of what you what designed. Sometimes it can even cut down time spent on designing your poster as well. As much as I would love to have ESP, I don’t, therefore can not foresee you wanting yet another logo in the top right hand corner instead of some negative space. Just jot it down on your already perfect* brief and email it to me BEFORE the due date.
*perfect means this A4 poster shouldn’t take 8 hours to design for you
