Mid-70’s. Great original deck including instructions and unheard of exterior deck wrapper with deck name, etc..
Magician states that deck of cards has all of the cards facing the same way except fro one card. You proceed to transmit that name to someone in the audience via mental control. You find the card in the deck and it is indeed facing a different direction. For the skeptics who think you pulled a fast one, you turn the card over and it has a different back color too! Fox Lake brand deck. Deck and instructions are near mint- Exterior wrapper has slight tears at top. Also known as Flash Cards but better known as Brainwave.
Some blurring on instructions is done on purpose, magicians never tell!
