This is a 242 page book with a bunch of different lessons and experiments involving electricity. This one was put out by Florida Power Corporation, and though it does not have a copyright date, there is an order form in the back for other literature, and it states the prices will be good through May 1st, 1969. This is a neat book for both its information if you want to tinker around with some electricity or you collect Reddy Kilowatt items. I have no idea what it is worth, so I'll go with $30.00 plus shippipng. . As usual, I pick a price, and if it doesn't sell, I'll reduce the price. If it sells for 30 and it is worth $250,764,846 then it's your lucky day.
