Elvira's House of Horrors Lenticular/3D Apron Cards.
The left card is a flip transition, showing the rules on transition when you change your viewing angle.
The right card is a 3D/Stationary Card. The depth shifts as you change your viewing angle.
It is extremely difficult to get good pictures of these. The effects are far more active in person, especially for the 3D card compared to the Simulated Image.
