Why have the poster ?

The poster must have the name of the presentation along with who is giving it. There must also be the place, time, and date. The name must be big and appealing. Along with graphics to explain the presentation without giving it out I have an image of a holographic car on my poster to appeal and send a message for the future. I may put charts or facts to display my information in  a more appealing sense. If not a chart then a quote for inspiration and validation for my theme. My color scheme will be neutral and sleek. I may change the font to make it match the theme.
