Cordially Yours

This is an unusual trick and one that creates mystery and surprise. It can also be customized according to the venues and type of shows. You show four double-blank cards. You place a colored sticker on one card and the sticker appears on every card. Then, three stickers disappear from the cards and all the stickers are on one card!

You will need four double blank cards (blank on both sides) and some stickers.
