Little phones for little calls.

I'm wondering what that tiny phone in Liz's hand is supposed to be. Perhaps in Dick Tracy's world it's a cell phone. I mean, they've got those wristwatch radios, so anything is possible. Although, if it is, I want to see the little rotary part of the phone that you have to keep in your pocket so you can dial. I'd buy one. Then again, perhaps the phone represents the kind of call you're going to receive. I think phone calls would be far less nerve wracking if the reason for the call corresponded to the size of the phone, so if the little phone rang, you'd know that it was just your friend wanting to know if you wanted to go get ice cream later, but if the big phone rang, it could mean that your friend had been in an accident. It would make life easier, though you might also live in fear of the big phone ringing, so maybe not.
