A miniature Mamiya film camera that fits snugly in one hand but weighs maybe two pounds. Loaded with all the fine-tuning adjustments one found in a regular-sized camera then.
The Kodak Instamatic, the most convenient piece of picture-taking equipment appropriate even in the hands of a child. Most households had one then, and the price was quite affordable.
What about a sturdy, industrial-strength, made of heavy cast-iron, one-hole puncher for your school work. Weighs maybe two pounds.
And a manually-operated numbering machine that produced professional-looking numbers, then at least. Number crunchers had to have one.
For the audiophile, a transistorized reel-to-reel tape recorder that one could carry around for listening to recorded songs or for interviews of important personages.
Those were the days.
ADDENDUM:
Call this your check protector. After writing out your check, roll this gadget over all the text and numbers you just wrote and viola, instant protection. It embosses and perforates the areas touched by it. A hardy and endurable product made in the good old US of A.
