There is a memorial digistamp over at Pink Cat Studios please go and take a look
"Lorie Ames has organized a way to donate for a memorial for Henry. Henry loved his local zoo and visited it almost every day in the summer. As a memorial, trees will be planted there in his honor. I’ve created a digital stamp to help raise funds for a tree for Henry.All proceeds from the sale of the digi stamp, minus Paypal costs, will go towards the tree. If you would like to donate, please visit this webpage to purchase the digi stamp."
