Interesting, Don. It's too big (83 X 102) to go within the auction description itself, according the the eBay regs, it's got to be 33 X 88 or smaller. But putting it in the "location" area would work, I don't think there's any reg about that. I've seen some pretty huge state flags and other goodies in that field.

Another option would be to put your photo within the auction description itself, then put this logo (with your personal membership number removed, of course), into the "image" field in the logo, so it appears beneath the actual description.

But, if someone with some graphic abilities could work up a complying 33 X 88 logo, you could incorporate an HTML string that would turn the button into a hyperlink to the Club website. Look at any PayPal logo/button to see what I'm talking about. Perhaps the link could be to a special page created just for that purpose?
