That is a giant sculpture of a head in the Main Square, and Francisco is picking its nose. Francisco was the other American couchsurfing with me in Krakow. He is in the army and based in Italy, spending the off time traveling around Europe. We spent the day walking around the town together, and yes, we are being stupid Americans in this picture.
This is a replica of the Shroud of Turin in Pope John Paul II's home church (the name escapes me now). Even though it is a replica, it is still considered a Holy Relic because it has touched the original. So if I touch Bob Dylan, can I be considered the world's best folksinger as well?
