THE BOB DYLAN CONVENTIONS...
They gathered fans
from all countries, founding there the opportunity to meet old pen-friends (no Internet at that time),
buy rare memorabilias, listen to rare music and watch video on large
screen. Sometimes, as in New York, an imitator contest was organized. Here
are some documents.
