I finally got a poster of Yu Li San, the medium that was part of Professor Alba's act and now I'm looking to know more about these people and the poster. The scant information that I can find about Alba and Yu Li San saws that Alba was a Spanish magician in the 1930s but the poster of Yu Li San is from 1959. This does not seem to match (see: http://www.the-forum.com/posters/alba.htm
). Does anyone know the history of Alba and the Yu Li San poster? Are the dates for each correct?
