When was the last time you saw one of these?

Once upon a time, these things had drug stores wrapped around them.
The pic is from the Web site of Retro Electronics and Audio Lab, a Texas shop that repairs jukeboxes, electronic organs, phonographs, antique radios and tube-type amplifiers. Check ’em out. The site also contains more than 3,000 photos “relating to the technology of yesterday.”
