Diana f+ keychain giveaway

On my trip this weekend to San Diego, we visited the Photography museum. I bought some goodies for myself, and picked up one for a giveaway. One of these days I'd love to giveaway a real Diana camera. {UPDATE: I've given away TWO Diana Cameras on this blog actually, here, and here. Dreams do come true, friends!} Until that time comes, I think the Lomography mini keychain is a great substitute.
I bought one for myself, the one I photographed is mine, but the one for the giveaway has never been opened.

The specs:
Made from ABS plastic, these 20% Lomography Keychains are miniature versions of the Diana f+ camera. They come in a small tin the size of a 35mm container film.

To enter the giveaway:
-Tell me what your favorite Lomography format is. All commentary is open to the giveaway but if you are a Lomo user, I'm curious to know!
-This is open to all international readers, you need not have a blog to enter, just leave an email.
-The giveaway ends October 11 in the evening and the winner will be chosen by random.org

- You must be a follower of our.city.lights, please let me know in the comment below. There are many ways to follow, just check them out on the left sidebar. I want this to go to my readers not just passerby's

For extra entries:

-If you post this button below on your blog to link back to this post, or tweet it, post a blog entry about it, I'll give you additional entries. Just maker sure you let me know, it'll make the giveaway so much smoother and I won't miss anyone.

Just to clarify, this is for the Diana keychain, not the Diana camera!
Thanks for entering!
