I'm currently doing volunteer work as the Technical Assistant for 3 connected web sites and I recently created a new logo for the main site as well as a banner for the header of the web site. Now there is a gift shop where you can buy items with the logo and/or the banner on them.
Here's the link for the gift shop:

The logo is at the top of the page. Laugh at Cancer is a non-profit organization dedicated to providing support for anyone who has been touched by cancer and their families.
