October will be a month of firsts for Island-raised artist Paul Carrick. This month, four of his paintings will be hung at the world’s only science fiction museum in Switzerland. “It’s the first time I will have my stuff on real walls,” he said by telephone this week. When he steps off of the plane in Switzerland to view his work, it will be the first time he sets foot in Europe. “It’s going to be an overload of stimulation,” the artist, 35, said.
