This is actually supposed to be the background for the instant printouts (the type where guests can use the props provided, pose for photos and get them printed out instantly at the printer station, in credit card size so that they can be slotted in wallets as souvenirs - we got this service included in our actual day photography package. Did spend quite some money on this but guests, esp relatives, enjoyed it so much that we felt was money worth-spent)
Will try scanning in the instant printouts after my holiday..
