Another take on this is "Comedy Card Babies" by Dave Devin,
Have spectator select card and shuffle into the deck. Magician states that before he came to the show, he made a prediction which he placed inside of the envelope marked with a question mark.
Magician asks spectator if they have any idea what was predicted into the envelope. Spectator answers "NO", at which time magician pulls prediction from the envelope with "NO" side facing audience.
Magician states, "You're absolutely correct, in fact, you were "right ON". When you say "right ON", then turn the prediction card end for end changing the world "NO" to "ON". This also puts you in position for your next prediction using the babies.
Magician now states that he has a prediction on the "other side" of the "ON" card. Ask a spectator to name a very famous person. Someone everyone will recognize. When the spectator names person, turn "ON" card over revealing Baby #1 picture, stating that "here he/she is at 6 months old."
Next, the magician states, "I know what you're thinking, what if I would have said Oprah Winfrey?" Open the prediction from top to bottom with prediction in this position (full size baby #2 facing audience). The 4 of hearts now faces magician. This puts the final prediction in correct position for final reveal!
