Do you remember real mailboxes? How about real mail? What about that feeling of excitement as you opened up that rusty old mailbox in hopes that something would be addressed to YOU?

It seems like much of that is lost nowadays. A letter addressed to us now means we probably owe someone money.

Well, we miss that feeling. So, we decided to start The Lil' Happy Invisible Creature S.A.S.E. Club. Inspired by our youth - when the simple task of addressing an envelope to ourselves, licking a few stamps and patiently waiting a few weeks could mean receiving anything from a signed baseball card from spring training to various stickers from our favorite skateboard company.

It's real simple. Send us a self-addressed stamped envelope and we'll fill it with goodies. Put 2 stamps on your return envelope and we'll fill it with more.

However, we thought we'd make it a bit more fun and interactive. Regardless of your artistic ability, we ask that your envelope addressed to us be creatively designed or illustrated. No rules, anything goes - and we'll post the coolest ones on the Lil' Happy Twitter page.

So, that's it! Oh, and we figured we should set some ground rules and answer a few questions. Just in case.

DEADLINE: September 1st, 2010 Please send us your S.A.S.E. by that date. We hope to do this once a year, but since we don't know the volume we'll be receiving, we have to shut off the valve at some point.

Please send your envelopes to: The Lil' Happy Invisible Creature S.A.S.E. Club, P.O. Box 375, Seahurst, WA 98062

Q: I can't draw to save my life. What should I do? A: Like we mentioned, it's regardless of your ability. C'mon, it'll be fun!

Q: What are you going to send us? A: We're not telling. It'll be fun though. We promise.

Q: When should we expect our envelope back? A: After the deadline sometime. It could take awhile as we also run a full-time studio over here. If you send it, it will come. A little patience.

Q: I don't live in the U.S., can I still participate? A: Probably not, due to customs. However, we aren't international mail professionals, if you can find a way that works via USPS, we'll definitely send it back! If it involves anything more than dropping it in a mailbox, we won't be able to pull it off. Sorry.

Q: Can I send you more than one envelope? A: No, sorry.

Q: Can I send a poster tube? How about a large document envelope or soft pack? A: Nice try. Let's keep this old school. Legal sized envelopes would be the biggest/best option.
