We did this for a rehearsal party awhile back -- since most of the guests were out-of-towners that night (in fact, most of them were out-of-country-ers), we decided to give them "Passports" to Canada when they arrived to the dinner. The passports worked twofold: The front said the guest's name and table number, then the inside held the menu (which we did like actual stamps in a passport). We had a lot of fun with this one; we even tucked a poem by e.e. cummings in the back; we didn't know at the time we designed it that he was the groom's favourite poet!
Apologies for the photos -- the first one is by a professional, the last two were taken with my phone!
