We feature cartoonist Jack Guinan's syndicated "The Closing Bell" here on Fool.com, but making light of the stock market isn't his only pursuit. Guinan has teamed with CureSearch for Children's Cancer to raise funds with a suite of greetings cards.

The selection includes holiday cards, birthday greetings, get-well cards, and more, and they can even be personalized. You can send a few to share a laugh with your favorite fellow investors, or to spark your friends and loved ones' own interest in the stock market. Look over the selection and place your order here. If you like what you see, use the "email" link at the top of this article to spread the word.

CureSearch, alternatively known as the National Childhood Cancer Foundation, has been rated "A" by the American Institute of Philanthropy. The Charity Navigator site notes that it spends 95% of its revenue on program work, and just 2% on fundraising. Corporations that have supported its work include AFLAC and Amgen. NASCAR champ Jeff Gordon also supports the cause through his own foundation.

Jack Guinan's cards might not only put a smile on the face of you and your friends, but also help brighten the days of patients and families fighting childhood cancer. Give it some thought and check out the available cards!
