At the end of your story, "Incognito", you asked for personal experiences of having taken a chance on buying work of an unknown artist. A few years ago, at the preview before a local auction, I was attracted to what I felt was a powerful work of art. This woodcut print, entitled "Adoration of the mouse" (numbered #1 of 25), was signed by the artist, but I could not make out his name. I had to wait hours for its sale, but acquired it for $1. Subsequent internet searches revealed both the artist's name, Jacob Pins (prominent woodcut artist), and the probable value,about $500 to $1500.
