An original signed etching by Pablo Picasso went missing in Milwaukee. It disappeared in broad daylight from the display case at an art appraiser's offices. "This is intentional," said appraiser Bill DeLind. "Somebody either knew what they were doing or just got lucky." Picasso was one of the 20th century's most influential artists. His paintings sell for millions of dollars at auction. The piece is valued at between $35,000 and $50,000.
