Dora the Explorer, Nickelodeon's cartoon heroine, celebrates her 10th birthday this month. On that occasion she has recruited a few celebrity friends to design one-off backpacks auctioned off for UNICEF in the United States, England, France, Spain, Netherlands, Mexico, Canada, Greece, Australia, New Zealand and Israel. Slash is on of them since he has designed a limited-edition bag which includes a sewn in label, with an original signature.
