Haunted Memories
These lenticular cards show a Victorian or Edwardian portrait photograph that has has an additional - slightly less flattering - image incorporated, so when you turn the card to and fro, the image changes from the normal picture to a more spooky picture!
Created by Edward Allen, the cards are 5 x 7 inches.
If you ever thought that one of your ancestors had a darker side, here is the proof. Best not show them though - they would be turning in their grave!
