Police have recovered two cardboard boxes believed to contain color slides of the Olympics destined for next week's issue of Sports Illustrated, a department spokesman said Friday.

The boxes, labeled "Seoul, Korea, Sports Illustrated," were turned in by a messenger this morning, said Detective Vincent Jones.The messenger, Roberto Garcia, 42, told police he had found them at about 4 p.m. Thursday at the northwest corner of 56th Street and 7th Avenue. He later showed them to co-workers at the Quality Messenger Service and then took them home Thursday night.

The co-workers heard news reports about the missing Sports Illustrated pictures and contacted the magazine, said Jones.
