A reader noticed the similarity between eBay's new ad campaign and my blog's banner (which was designed by Donna Mae Montgomery, an artist and illustrator).

The website for eBay's Windorphins campaign playfully urges people to get some of this natural, addictive substance that delivers "a general sensation of unabashed joy in the brain, leading to heightened energy, exuberance and outright slam dunk high-five behavior."

Sounds not unlike the dopamine rush of romance. And, the site's header does have a similar look to my banner. Think I should sue?
