Only came upon this site today,check out these photos of materialisations.....For you sceptics remember that all these photo's were taken under strict laboratory conditions and in the prescence of the best scientific minds of the early 1900's.
Also remember that they come from all round the world and show extraordinary similarities in method and form.
This is the best site i've ever seen on this subject...enjoy..!
