This sticker is the logo for the Donate Life organization, an organization dedicated to public education and awareness for organ donor programs.
This is a donation sticker, which means that 100% of the purchase price of the sticker (yes, all $5) will be donated to Donate Life Wisconsin. I picked this organization because I am an organ donor myself (donated a kidney in April of 2017).
If you would like to donate outside of buying a sticker, the link is: http://donatelifewisconsin.org/get-involved/
Sticker is 4" square.
