From my personal collection which is in its infancy.
On the left: Panasonic T-53 Six Transistor shirt pocket radio. Takes a standard 9V. Works.
On the right: Magnavox AM-80 Eight Transistor shirt pocket radio. Takes some kinda crazy battery like a round 9V. I’ll have to look into it more. I’m not sure if it works. This one is near mint. The Top Grain leather case is marked Ak Sar Ben 100 Club.
Upon some quick research, Ak Sar Ben is Nebraska spelled backwards and represents a community among other things in Omaha.
I’ve decided that these are the types of radios I’d like to collect rather than the larger tube table tops and portables. I still respect their beauty immensely, but I just don’t have the space.
I hope you enjoy.
