People are attracted to aesthetics (beauty) regardless of any other factor in your marketing.

It's simple. People like beautiful things better than ugly, or even just plain things.

Beautiful women, starry skies, mountain vistas, a laughing child, a car that looks like it's ready to leap into the sky and pass light speed - people LIKE these things.

All by themselves, they create an attraction. That makes it more likely someone will read your piece and will have a favorable impression of it. They are more likely to hold on to the business card or brochure, to bookmark the website, to remember your message.

This may be "sensible" or not. But, like celebrity endorsements, it works.

A lot of times beauty is the only thing a marketing item has going for it. There's a lot more to marketing, but it's a good start.
