When a businessperson makes a presentation she really needs to be prepared. Every detail must be just right and the text of her discussion must be carefully rehearsed as if she was preparing to sing the lead in a production of "La Traviata." These days, a presentation is most often prepared using a computer software program like Powerpoint. It's now considered perhaps a bit quaint to present a series of pre-printed posters on a presentation easel, but it's a better idea than you might think; it is unusual and memorable.
Easels are available in all kinds of shapes and sizes, from small tabletop models to larger deluxe types that you might imagine holding a classic work of art like Leonardo da Vinci's "Mona Lisa" or Van Gogh's "Starry Night." They are also available in a wide range of prices. The important thing is that you get one that helps you make your point. How awful it would be to do all the work of preparing a big talk with an outstanding visual presentation, only to have it ruined by the wrong presentation easel.
