Two Little Mistakes by Steve Shufton

She selects a card and goes to WHATEVER EXTENT NECESSARY to hide its identity from you, the all-knowing magician! With EMPTY HANDS, two BLANK CARDS are shown FRONT and BACK. She becomes STUNNED to discover a miniature card has magically APPEARED between them! BUT, it's the WRONG CARD!

The two (and only two) blank cards are shown again front and back, when suddenly ANOTHER miniature card APPEARS between! BUT, it's the WRONG CARD again!

After the two BLANK cards are shown front and back once more...

Inexplicably,
ONE of the BLANK CARDS becomes HER SELECTION!!

ABSOLUTELY MAGICAL!
NO PALMING! NO SLEIGHTS! NO POCKET WORK!
