In 2006, Thumbtack Press raised $1,000 for St. Jude Childen's Research Hospital with a giving challenge, but that was a "drop in the vast sea" when it comes to cancer research.  This year they are going to donate over $3,500 with your help.  Bob Dob has graciously donated all of his commissions for his "Lonely Day" print ($75 ea.) for the cause.  Likewise, Thumbtack Press will donate all proceeds of this print run to St. Jude... Every single penny.
