In celebration of the Girl Scouts 100th Anniversary, the Blackwood Post Office of Gloucester County as well as other post offices around the nation, asked Girl Scouts to design cancellation stamps to be used to cancel all mail on June 30th. On June 30th the Blackwood Post Master, Sharon Rein, acknowledged Anna, a Washington Township Girl Scout, for her cancellation stamp design. The cancellation stamp, which was used to cancel all mail on June 30th, featured a globe which represented Girl Scouts and Girl Guides from around the world.
Anna received a Certificate of Commendation and an enlarged version of her design from the post office. Girl Scouts from as far as Mt. Laurel came out to the unveiling and received a copy of the cancellation stamp design. The stamper is still available at the Blackwood Post Office for cancellation until August 30, 2012.
