SALT LAKE CITY?The first of 11 gigantic images of Olympic athletes has gone up on a downtown building. By mid-January, nine more office towers and a building at the University of Utah will be similarly transformed.

The building wraps, measuring as much as 141 feet long and 97 feet wide, will depict winter sports athletes, including a figure skater, snowboarder and Paralympian.

The first image, a photograph of a downhill skier, began unfurling over Key Bank on Tuesday.

“It’s much like a window washing operation, where we work down in sections hanging the banners,” said Scott Givens, director of Salt Lake Organizing Committee’s creative group.
