A friend has found an oil painting rolled up inside a wall. He described it as about 24X16. It used to be framed. The signature reads A. Phalipp or Pholipp (or perhaps Philipp but probably not). It is a picture of a young boy around the turn of the century maybe earlier. He is a redhead with blue eyes. The background is green. Has anyone got any info on this or suggestions on where to look? Thanks.
