If you know a preschooler, chances are you know Dora the Explorer. Though the sassy Latina character will always stay 7 years old, next weekend marks her 10th anniversary on Nickelodeon. To celebrate, the network has created the Beyond the Backpack campaign, which kicked off this morning at the famed Macy’s flagship in New York City’s Herald Square. As part of the initiative, 12 one-of-a-kind backpacks—Dora’s accessory of choice—designed by stars like Jessica Alba, Heidi Klum and Salma Hayek will be auctioned off to benefit the Children’s Defense Fund. Want to give the Dora fan in your life the ultimate gift for their first day of school? Head to CharityBuzz.com to place your bid now!
