Since 1986, National Park visitors have used the Passport to Your National Parks® program to preserve memories of their park travels by collecting ink cancellations at every park they visit. The National Parks of Boston are happy to provide physical stamps, but also virtual cancellation stamps for our visitors to download, print, and paste into their books. Keep coming back as we add more virtual versions of these stamps in the future!
