This is my first mail art I have received.  I was so excited to find these in my mail box.
I think decorated envelopes like these make it even more special to receive, since I know how much more time and creativity was put into them, besides the written letter, which of course is always special. 
This was one came from a participant from Swap-bot for the Beginning Mail Art swap.  I really love it and I was so happy to receive it.
I love the stamps too and it's my first Owney stamp.  So cuuute!!!
That's the back of the envelope.  I really like the notes and butterfly.
And inside I found a nice note and this very cool magnet, which I love, since I'm a big fan of the classic movies like this one showing Humphrey Bogart and Ingrid Bergman in Casablanca. 
This cool envelope came from a nice lady right here in Virginia, who contacted me to be pen pals.
It's great isn't it?  Her stationery was really neat too, with a typewriter on the writing paper.  (Sorry, I forgot to take a picture of it.)
And as a bonus she included a bunch of little goodies, like tags, tickets, stamps etc. I can use for mail art projects.
Thank you again to both ladies for sending such great mail!
