We like 46 and 48 the best. The only concern is with how the 2 will look on letterhead. We don't want it to "wash out" if it is on white paper. Maybe on 46, if you put a brighter color in the boxes of the building that will contrast because the 2 is the clearest on that design. Very original and cool - we really like this concept. The owners will definitely see one of these. - thanks
