Someone draws a picture of (any) playing card and that actual card is found to be inside an envelope which has been in plain sight the entire time.

The freely thought of card is actually in the envelope and there is absolutely NO SWITCH:

• They can think of any card from a deck of 52, including the Joker. There is NO FORCE.
• They can change their mind, right up to the point where they sign the picture.
• The "prediction" envelope is in plain sight BEFORE the effect begins.
• The handling is super clean. There are no suspicious moves.
• The card is seen inside the envelope right before it is POURED DIRECTLY INTO THEIR HAND.
