What trick is this?

[FelixTK]

I have a set of cards but no idea where I got them or what the trick is. They consist of the following 4 cards:

Ace of Spades with a Dual Queen of Hearts/Spades on the back
Ace of Clubs with a blue back
Ace of diamonds with a dual Queen of clubs/diamonds on the back
Ace of hearts with a blue back

Any help, even a name of the trick, would be appreciated.
