The first radio to sell for less than $10.00, the Crosley "Pup" was advertised for sale at only $9.75. These are hard to find as they were small and inexpensive and most were just tossed in the trash when they quit working or were replaced by a more sophisticated set. This one works quite well, is all original, complete right down to the bottom cover with label (which is often missing) and it has the original connector leads with the battery ID tags (also often missing). Battery operated, all that is needed is an "A" battery of 1.5 volts (if operated with the correct WD or WX-12 tube, they will work quite well with a UV or UX-201A plus a 22.5 volt "B" battery or equivalent power source, antenna and headphones. satisfaction is guaranteed.
