Here's a very nice and very rare dealer's sign for authorized agents of DeForest Radiophones. 

Sign is made of metal and dates to either 1920 or 1921. As you can see in the photos, its condition is quite nice. 

No touch-ups, no tweaks, no damage, no funny business -- just some scattered scratches adjacent to the "radio waves" near the top. 

Features a wonderful image of a child listening to the world on a DeForest Interpanel set, which was the company's flagship radio from 1920 to 1922.

Sign measures 19" x 13". 

A really beautiful sign from the advent of radio broadcasting. Guaranteed to be authentic. 

I'm one of ebay's best known, most highly regarded sellers of antique radios, and I specialize in radio and radio-related items from the 1920's. I've been selling and shipping them for more than 25 years. Regardless of what you purchase from me, you can rest assured that your purchase will arrive safely because it's been carefully packed (by me, not by some well-intentioned but nonetheless confounded, doe-eyed teenager working at the UPS store who wouldn't know a radio from a rocket ship), Sure, you can probably get a lower price from Joe and Janet Barn-Find, but when your "bargain" arrives broken, and without any hint of how you might be able to put it back together, you'll realize that you really do get exactly what you pay for.
