I'm sure this is not unique to my office environment: the cleaning staff will not throw anything out that isn't in a garbage can unless it has a dayglo orange sticker on it that proclaims its trashiness in three languages ("PLEASE THROW OUT, POR FAVOR TIRALO, PROSZE WYRZUCIC"). Very utilitarian, and has probably saved my bacon a few times when important, but scruffy looking, boxes have drifted a bit close to the trash can.
During the big office purging going on right now, I came across a whole pad of these 5"x7" cards. Look at the jaunty Admiral in his washtub boat. Check out the gorgeous, and slightly irregular, waves across the bottom. Are you ready to throw something out already, just to have the chance to use this guy?
