The listing, VINTAGE 'MAGIC BRAIN" POCKET CALCULATOR has ended.
Here's a golden oldie! Before Texas Instruments was in every kids' backpack, you could get a Magic Brain Pocket Calculator to help you with your business, shopping and schoolwork! This is worth having for the instruction sheet alone which promises "in a few weeks you will be doing your mathematical calculations as fast as adding machines many times the cost of this instrument."
I'm sorry, I don't. I would guess pre-1970's, since there was no such thing as an electronic pocket calculator until I was about to graduate high school.
