This is a fun routine that first appeared in Allan's Magic Mafia book. It is based on a Dai Vernon plot from the 60s. However, a typical 'all backs' routine requires many moves - half passes and double lifts. Here Allan has engineered a routine with a lot less moves. You could even do this routine while maintaining a stacked deck.
You show a deck that consists of cards that have backs printed on the front and back. This changes then to faces on both sides of the cards until everything goes back to normal.
