In 1963, Analog was a large format monthly magazine,
part slick and part pulp, with a cover price of 50 cents. Its
eclectic readership and contents attracted some curious
advertisements, such as this one from Leesona Moos Laboratories
for aerospace devices self-powered by Krypton 85 nuclear batteries.
How many Analog readers in 1963 assumed that in a
couple of years there'd be nuclear flashlight batteries for sale
at the hardware store? This one certainly did.
