This Closer Than We Think! strip ran in the December 25, 1960 Chicago Tribune.
Chistmas cards of the future may be transmitted electronically. The post office is studying the use of space technology for quick movement of endless quantities of mail between widely separated points.
To do this, microwave stations would be set up. Envelopes would be opened mechanically, and the automatic "fingers" would remove the contents and expose them to a scanner. Impulses from the card or letter might be beamed to a postal satellite or even the moon, bounced back to the destination point, reproduced there in the original printing or handwriting, sealed in a capsule and delivered. All this might be done minutes from the time the communication first arrived at a post office thousands of miles away.
