Here's an interesting array of cordless radios
Upper left...An 8 transistor Panasonic from the late 50's
Upper Middle...A radio that mounts on your bicycle circa 1965..
Upper Right...The straw is the antennae..hehehehe
Lower Left...This radio works great, I don't know when it was made though!
Lower Middle..This radio is water proof, you can hang it in the shower!
Lower Right..This 'crank' radio also works on solar power...hehehehe
This is just a drop in the bucket!!
