I have no time to discuss the details here, but according to the
articles "Edward Larssons alfabet" and "Edward Larssons alfabet och
Kensingtonstenens" by the Swedish linguist Tryggve Sköld - found at
http://www.sofi.se/daum/katta/katta13/katta13.pdf - there is a quite
significant probability that the Kensington Runestone is a 20th
century creation.
