The "Roadshow" rolls into San Francisco for three shows (taped in August 2003). In the opener, host Lara Spencer checks out porcelain all over town. At the Moscone Center, items appraised include an 1850 vase, a print from a post-office mural depicting the city's 1934 longshoremen's strike; jewelry made during the Gold Rush years; an 1890 Ute doll cradle; a Maynard Dixon painting; and a baseball signed by the 1933 San Francisco Seals of the Pacific Coast League. One signee: Joe DiMaggio, who hit in 61 straight games that year
