Visual Thinking for Business - Make Your Point
I've tried a little to find a good visual for a telephone. It is interesting that the picture of an "old" telephone still works very good. And it is interesting that it is not that easy to doodle a telephone earphone i a convincing manner.
I asked myself if it is better to have a telephone cable or not.
Nice work! the cable might help you in a "live-situation" in which your phone did not work out too well and you want to add another convincing detail. And it is always good to have variety!
