Invitations

I'm looking into various invitations to events and how they have creatively promoted them. I want to create something interactive but yet simple like a lot of these below.

I like the idea of creating a mail out kind of invitation because this would be quite mysterious not knowing what it is, but it could also go the other way where people would just through it away and not bother to look at what it is.

This idea of placing the promotional details on a plectrum works so well and is consistent throughout the campaign. Using such a small tool for promtotion is a great idea because it's not a hassle for people to keep, it's intriguing and can be used for another purpose as well.
