Stamp Out Childhood Cancer

As of January 2020, the USPS Office of Stamp Services has officially accepted The #Americanchildhoodcancerorganization (#ACCO) application for the childhood cancer semipostal stamp. The next step towards finalizing the USPS approval is demonstrating America’s support for this stamp from those who share our passion for our nation’s children diagnosed with cancer.
