I like to use cartoons in corporate newsletters to make a point in a humorous way. Andertoons has a great selection and the site is easy to use.

These 12 cartoons are my very top sellers. Not surprisingly they're largely business and sales themed, but there are a few surprises too. (Who knew defibrillators would be so popular?)
I hope you like them as much as myself and others do.
