You've Got Mail - And I Mean Real Mail!

 This odd little character is a card.

He is a Dolli-Gram.

 He arrived with an actual 3d version of himself.

 Can you imagine receiving this box in the mail in the 70's? 

I would have sent them to everyone.  

Now, I have to hunt them down on Ebay and send them to myself.

 When you bought the doll, the card was something you were meant to cut up.

 You chose the right sentiment to enclose in the box with the doll.

 Isn't this brilliant?

Dolly-Gram by Western Union!
