Stumbled upon this the other day:
A mighty fine idea, the old tin can tradition is something of a rarity these days, refreshing to see them make a comeback in a contemporary format. visit the site the see the rest of the images. the invitation is inside the can, you can RSVP to the event and the guest brings it to the wedding to be attached to the bridal car, brilliant!
Genius spin on the classic wedding invitation
